Bug Description
BugLink: https:/
[Impact]
On systems with AMD Picasso/Raven 2 GPU devices, when the IOMMU is enabled, the system fails to boot correctly, and all users see is a black screen.
This is caused by a null pointer dereference when enabling the IOMMU after the device has been initialised. It should happen the other way around.

A workaround does exist. Users can set "nomodeset" or "amd_iommu=off" to GRUB_CMDLINE_
[Fix]
The regression was caused by the following commit that landed in 5.15.0-112-generic, and 5.15.150 upstream:
commit 3c7e53c0d4b43ff
Author: Yifan Zhang <email address hidden>
Date: Tue Sep 28 15:42:35 2021 +0800
Subject: drm/amdgpu: init iommu after amdkfd device init
Link: https:/
The fix is to revert this patch, as it was not suppose to be backported to 5.15 stable.
The mailing list discussion with AMD developers is:
https://<email address hidden>/
The fix hasn't been acknowledged by Greg KH or Sasha Levin yet, so sending as a Ubuntu SAUCE patch. If the upstream status changes, we can NAK and resend.
[Testcase]
You need a system with an AMD Picasso/Raven 2 device. It will likely be an APU, and not a discrete graphics card, but any AMD Picasso/Raven 2 device is affected.
Install the kernel and boot. Make sure full modesetting is enabled.
There is a test kernel available in the ppa below:
https:/
If you install the test kernel, your system should boot successfully.
[Where problems could occur]
We are reverting a problematic patch and going back to how it was before 5.15.0-112-generic. This should not cause any issues for users.
If a regression were to occur, users can set "nomodeset" or "amd_iommu=off" to GRUB_CMDLINE_
The impact of a regression would be high, as users displays could be blank.

As bizarre as it is, this commit was actually originally included in 5.15-rc5:

It seems to have caused issues back then too, and was removed in the following fixups, in 5.16-rc1:
commit 93cec184788b0cf

I'm not exactly in favor of rewriting history twice, so I think we should just revert the upstream stable patch and move on.

Attached is an annotated copy of my system log with the relevant update from 107 to 112, the failed boots with 112, a successful boot with the last good kernel 107, and a boot with 112 using the workaround. Search for BOOT in capital letters to find the start of each boot. I hope this might be helpful.
I am no expert, but perhaps these lines might be relevant, as they only seem to occur on the failed boots with 112:

I had the same issue, similar hardware I have had to revert back to the previous kernel version 5.15.0.-107 there was some errors in the log that pointed at the AMD GPU
if you need to boot from the previous kernel you will need to tap shift when the device boots, go into advanced options and select
kernel .107 generic
I then changed my grub menu
sudo nano /etc/default/grub
changed
GRUB_DEFAULT=0
to
GRUB_DEFAULT="1>2" (this tells grub to boot into advanced options and then the second linux kernel image, .107 at least for me ) save the file
sudo update-grub
sudo reboot
The device then booted successfully into the working .107
then i removed the .112 kernel
sudo apt remove linux-image-
sudo apt remove linux-headers-
sudo update-grub
I also put a hold on .112
sudo apt-mark hold linux-image-
sudo apt-mark hold linux-image-
apt-mark showhold
I then changed grub back to
GRUB_DEFAULT=0
I have attached a full log for the developers perusal

AFAIK It's a bad backport to 5.15 stable. If it's what I think, here's the fix (IIRC).

Try applying that to your 5.15 kernel.

Hi everyone,
Mario, that does indeed look like the relevant fix on the stable mailing list.
It reverts this commit:
commit 3c7e53c0d4b43ff
Author: Yifan Zhang <email address hidden>
Date: Tue Sep 28 15:42:35 2021 +0800
Subject: drm/amdgpu: init iommu after amdkfd device init
Link: https:/
It arrived in 5.15.150 stable, applied in 5.15.0-112-generic.
Interestingly enough, this was once applied during the 5.15 development cycle
in 2021, in 5.15-rc5:
commit 714d9e4574d5459
Author: Yifan Zhang <email address hidden>
Date: Tue Sep 28 15:42:35 2021 +0800

Bizarre. It seems to have been removed back then as well.
Anyway, it seems it is on track to be once again reverted in the stable mailing list thread that Mario linked.
https://<email address hidden>/
To make sure this is the commit that is causing you issue, I have built you test kernels with the above revert commit applied.
There are builds for 22.04 and 20.04 HWE.
I only just uploaded them, so give them 3 hours from this message to build before trying to install. You can also check build status here:
https:/
Please note this package is NOT SUPPORTED by Canonical, and is for TESTING
PURPOSES ONLY. ONLY Install in a dedicated test environment.
Instructions to Install (On a focal or jammy system):
1) sudo add-apt-repository ppa:mruffell/
2) sudo apt update
3) sudo apt install linux-image-
4) sudo reboot
5) uname -rv
Look for "5.15.0-
Can you boot into this kernel and let me know if it fixes the problem? If it does, we will chime in upstream, and get this included, and we will land it in the next Ubuntu kernel release.
Just give the kernels about 3 hours to build first.
Thanks,
Matthew

CPU: AMD Ryzen 3 2200G, 4x 3.50GHz, boxed (YD2200C5FBBOX)
Graphics: AMD Vega 8
Kubuntu 22.04, fully updated today
Expected:
PC starts
Actual:
PC monitor stays black after logo of mainboard manufacturer.
Attempts at fixing this:
Because I had problems with startup where the addition of "nomodeset" in GRUB helped, I tried this. This time it did not help. The computer actually started - more than before - but got stuck at various stages of the boot process.
The PC would not fully start with kernel 5.15.0-112-generic.
I chose 5.15.0-107-generic in GRUB. 107 worked without a hitch.
At the moment the workaround is simply using 5.15.0-107-generic.

Hi Tino,
It says Fix Released for Ubuntu, aka, the latest Ubuntu release, which is 24.10 Oracular, as it isn't affected. Maybe I should have marked it invalid in the first place.
Anyway, once someone tries the test kernel I built yesterday to see if it fixes the issue, I can go about getting the patch into Jammy's 5.15 kernel.
Thanks,

Hey,
As of now, the update to 5.15.0-112 is still getting proposed in the update manager, meaning that with automatic updates your computer might fail from one boot to the next, would it be possible to pull it from there?

Today Update Manager updated my Kernel from 5.15.0-107 to 5.15.0-112. Unfortunately 5.15.0-112 is not compatible with the AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx x 4 graphics processor in my HP model 14-dk0011na laptop resulting in a black screen.
Via GNU GRUB menu booted into Linux 5.15.0-107-generic from the list, and once into the OS using Update Manager removed 5.15.0-112.
The laptop now boots correctly using Kernel 5.15.0-107.
Looking forward to a fixed version of 5.15.0-112
How will novices like myself know when the 5.15.0-112 kernel is corrected without having to go through the above cycle every few days please?

Hi everyone,
I spoke with Stefan Bader of the Kernel Team again. They are planning to include
the patch in a respin of the current 2024.06.10 SRU cycle. https:/
I will let you know once the kernel has been built and placed into -proposed for
verification.
But at this stage, as long as the respin occurs, this should be released the
week of 8th July, give or take a few days, if anything else pops up.
Thanks,
Matthew

Hey,
After disabling the kernel update via the update manager, it now got installed again, again resulting in a not working system.
Isn't it possible to just completely remove this one version from the repo?

Hi all,
Same problem: No problem on 5.15.0-107.117 and 5.15.0-112.122 shows black screen after GRUB.
Same hardware: AMD Ryzen 5 PRO 2500U w/ Radeon Vega Mobile Gfx
It's both funny and disappointing that a clinfo fix caused my first crash in 5 years on my daily driver.
In my opinion 5.15.0-112.122 should be blocked since it prevents multiple generations of Laptop and Desktop APUs from booting.
Special thanks to Barry K. for bisecting!
Thanks Armin W. for driving the fix and everyone else for your inputs.
Take care,
Willem

I have noticed one more consequence of this bug, which can be very painful for those who are running thier own servers. Regardless that it is possible to connect by SSH and operate server normally, in my case when I was trying to reboot it whole power down procedure is carried properly up to closing of journal, but server freezes at the end and is not restarting, so if one is far away from infrastructure, can be in trouble. Fix with nomodeset is solving this restart issue.
My server is on Ryzen 3 + Radeon Vega integrated GPU.

Yes, I agree with https:/
I updated to -113 today on Kubuntu 22.04. There is no improvement on -112.
The only things that is a workaround for me is "nomodeset" in GRUB or using the -107 kernel.
Updating to -113 kernel leaves black screen, backlit, on restart.

Same on 5.15.0-113, no improvement. I still select 5.15.0-107 manually on boot screen. I hope this won't be removed because the 5.15.0-112 is gone now from GRUB
I Have an AMD Ryzen as well

Hi everyone,
The patch was not present in 5.15.0-113-generic, as this kernel only contained
CVE fixes.
It should be in the next kernel update. Still waiting on the Kernel team to
respin.
I will write back as soon as we have a kernel tagged and in -proposed to test.
Thanks,

Unfortunately, I still have the same problem, after updating, I power down and restart, I get:
error: file `/boot/' not found.
I view the Kernels in the update manager, it shows 5.15.0-116 is "installed" and "supported until April 2027"
The Kernel is loaded and installed but "not found"
Then another window opens and I must choose "Boot from next volume"
Then another window where I'm given the choice of booting from 5.15.0-107-generic (on /dev/sda5)
This new Kernel is not listed at this window, not sure why not, seems it should be.
If I can give you more info. let me know.

Not sure if I'm replying correctly, this bug fix did not help me.
Unfortunately, I still have the same problem, after updating, I power down and restart, I get:
error: file `/boot/' not found.
I view the Kernels in the update manager, it shows 5.15.0-116 is "installed" and "supported until April 2027"
The Kernel is loaded and installed but "not found"
Then another window opens and I must choose "Boot from next volume"
Then another window where I'm given the choice of booting from 5.15.0-107-generic (on /dev/sda5)
This new Kernel is not listed at this window, not sure why not, seems it should be.
If I can give you more info. let me know.

Why in my Update Manager when viewing the Kernels, 5.15.0-116 is shown as "Installed" but not "Active"?
And when powering up I get: "error: file `/boot/' not found"
Maybe this is the problem and not the new Kernel?
Thanks, Ralph

Unfortunately, I still have the same problem, after updating, I power down and restart, I get:
error: file `/boot/' not found.
I view the Kernels in the update manager, it shows 5.15.0-116 is "installed" and "supported until April 2027"
The Kernel is loaded and installed but "not found"
Then another window opens and I must choose "Boot from next volume"
Then another window where I'm given the choice of booting from 5.15.0-107-generic (on /dev/sda5)
This new Kernel is not listed at this window, not sure why not, seems it should be.
If I can give you more info. let me know.

I noticed when the new update Kernel was loading this information, don't know if it will help...
Thanks again,

Hello Erv,
Just wanted you to know what I did and found out.
I tried the update grub command when I was in Linux mint OS, it did not have any effect.
Then I remembered reading somebody else has the same issue, no effect until they went into something else on their computer, it had 3-4 letters, I didn't understand, they said the update worked from there because they had loader that software before their Mint software.
So since I used to use UBUNTU, and still have it on my computer, before I loaded Mint, I figured I'd open my UBUNTU software and run the update grub command, then went back into Mint and it worked, I am now running 116 Kernel update. Good news, but my computer still shows that it cannot find that "boot" file, not sure but then I load the "next volume" and then I can choose to run either Windows, Ubuntu or Mint, so I'm good.
Thanks for your attempt to help Erv.

Yes this kernel update did the trick after running the sudo update-grub command from my Ubuntu software and then going back into my Mint software.
Thanks Linux team.

@Roger Ramjet> Glad you're making progress. GRUB can be a pain. I've been
there. The secure boot and BIOS/UEFI plus installing grub on multiple
drives but only one drive's GRUB is active.. sometimes makes kernel updates
on other drives two step chore, minimum.
You might try changing which volume is your primary boot drive in your BIOS
to your Mint drive? Have your backups up to date and volume-OS's
identified before that. Or not. Best luck and speedy recovery.
