Bug Description

Using a Dell Poweredge T20 and Ubuntu 16.04 with the 4.4 Kernel.

Just got the Meltdown update to kernel linux-image-4.4.0-108-generic but this doesnt boot at all. It just hangs after grub. There is no logs from syslog or such. SysReq Keys dont work neither.
The last kernel linux-image-4.4.0-104-generic still boots fine.

Achim Behrens,

Is the kernel that fails really 104? Or is that your backup that you just booted into to report the problem?

The one that fails for me is the new one, 108. It just "panics" nearly instantaneously.

Hi - just did update and also had issue where boot failed to progress - bit hard to tell what was happening as the HDMI video had not come up at that point. had to revert to 4.4.0-104. Running on Intel NUC Celeron(R) CPU 847.

Hi, Just did an update this morning to 4.4.0-108-generic and the boot failed to process. I restarted the system and entered the Grub screen where I received advance options to login. I am though able to login with 4.4.0-104-generic. I am not proficient in Ubuntu commands. If you want I can run the commands and share the screenshots.

Same here on a HP Microserevr Gen8, Celeron CPU G1610T. There seem to be problems in other distro's as well, a collegue informed me. F.I. 4.14.12 Debian (package naam 4.14.0-3) can't compile Nvideo modules etc., etc.
Back to the drawing board!

I'm having the same problem, no boot with 108, works fine with 104, on a machine with Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz and NVDIA proprietary drivers. The boot process stops almost immediately.

I took a picture of the kernel error message (attached), apologies for the poor quality, but it is the best I could manage.

I can verify 4.4.0-108.131 panics on a Dell Poweredge R630 (Xeon E5-2630) and a Fujitsy Primergy TS140S2 (Xeon E3-1220) and my home server (Core i5-4670), exactly as described on comment #4 by Alexis.

On the Fujitsu Primergy server linux-image-4.4.0-108-generic_4.4.0-108.131~lp1741934_amd64.deb (ref comment #3) runs fine, i.e. it does not panic.

We have a lab with 40 machines, where we just turned off auto-updates. Would be nice to know what the issue is ;)

Thanks in advance.

@3 i will try your kernel builds right now. I cant take a screenshot since there is just a blank screen.

@4 i did run ubuntu-bug on the booting kernel, which is the older one.

I just saw Dell offering a Bios/Uefi update. I will flash that after trying the test-kernel from @3

Achim Behrens (k1l) wrote :

ok, the kernel from #3 didnt work. still the same issue, just doesnt do anything after grub.

will try the new bios from dell now.

I have no video display when it crashes. If I boot in recovery mode, it only displays (translated in English) :
Loading Linux 4.4.0-108-generic...
Loading initial ramdisk...

And nothing else happens.

NB : my root partition is encrypted with LUKS

I have the same issue in Ubuntu 14.04

ok, updated the BIOS, did not change.

if i boot the linux-image-4.4.0-108-generic_4.4.0-108.131~lp1741934_amd64.deb from #3 it hangs after:
Loading Linux 4.4.0-108-generic...
Loading initial ramdisk...

when running the recovery mode, when booting the regular mode it doesnt show anything.

However another computer with 2x Dual-Core AMD Opteron 2212, motherboard S2927 (TYAN) boots fine.

While trying to get the BIOS update to a USB-Pendrive i found out on my Thinkpad x230 running 17.10 the latest kernel update make the USB not working properly :/
It show all usb pendrives as write-protected, while with the older kernel they do work. i will open another bug for this, when i can reboot to that kernel again.

Same problem, "Kernel panic" after 4.4.0-108.131 update.
No way to reboot, even from a network boot.
I can log in rescue, which runs a different kernel in my case (OVH) 4.14.12-mod-std-ipv6-64-rescue

Just saw 109 has been pushed to the repositories. Updating to that now works fine where 108 crashed.

4.4.0-109, which is now available as security update from regular Ubuntu repositories, works on all three servers of mine which panic'ed with 4.4.0-108. Thank you Ubuntu kernel team!

How can I find 4.4.0-109? I have tried to update with Ubuntu Software and 'about this computer' from the settings icon in the taskbar. Both methods tell me that my system is up to date and I can't find 109 on any of the Xenial repos. Thanks

I'm still having problems even with 4.4.0-109. This is running Ubuntu Mate 16.04 on an Intel Core i5-3570K with onboard graphics and luks disk encryption. Although the system gets a little farther than it did with 4.4.0-108, the password screen comes up in low resolution mode and does not respond to keyboard input, apparently crashed. So for now I'm back to running 4.4.0-104.

@Carter Braxton, Can you open a new bug for the issue you are seeing? Also, please add the tag 'pti' to the bug.

Thanks in advance!

Many thanks to the Kernel Team for this speedy fix!

4.4.0-109 fixed the problem

Carter Braxton (cbraxton) wrote :

@Joseph Salisbury,

It's working now. Previously I had uninstalled, but not purged, the 4.4.0-108 kernel. I purged the remains and reinstalled 4.4.0-109, everything appears to be OK now running the new kernel.

@Carter Braxton

Having the same problem with you. But now it's working. Thanks for the tips. For those of you having the same problem with me and Carter Braxton (low resolution in 4.4.0-109 kernel). You need to PURGE all 4.4.0-108 kernel image and the remaining HEADERS. Use command: sudo apt autoremove
