Modprobe doesn't recognize any parameters on 3.10.0-4

[Kelly Hyde]

After updating today to kernel 3.10.0-4 on Ubuntu GNOME 13.10 (Macbook Pro 8,2), I am unable to boot graphically. Recovery mode boot works fine. When attempting to boot using integrated graphics, the syslog gets spammed with this sequence of errors over and over:

Jul 19 19:07:09 polarimetric-MacBookPro acpid: 1 client rule loaded
Jul 19 19:07:09 polarimetric-MacBookPro kernel: [ 26.475546] i915: Unknown parameter `modeset'

Jul 19 19:07:09 polarimetric-MacBookPro acpid: client 1432[0:0] has disconnected

This error only occurs if modprobe parameters are passed at boot, so the problem appears to be with modprobe. All module parameters are said to be invalid. After boot, attempting to insert a module results in the same error.

EDIT: Please ignore the version string in the below information; I'm reporting this bug from 3.10.0-3 but it only affects 3.10.0-4.

[Brad Figg (brad-figg)]

This change was made by a bot.

[cacula (cacula)]

also problems with nvidia and new kernel 3.10.0-4 x64 on ubuntu saucy (unity). with previous kernel 3.10.0-3 there were no errors.
really strage behaviour with keyboard, mouse. system is unusable. had to revert to 3.10.0-3.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jean-Louis Dupond (dupondje)]

Same here with Optimus system:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 540M] (rev a1)

3.10.0-4 is broken, 3.10.0-3 works fine.

The -4 kernel gives following error:
Jul 20 22:08:03 laptop-jl kernel: [ 22.626903] i915: Unknown parameter `i915_enable_rc6'

[Kelly Hyde (polarimetric)]

@Jean-Louis Dupond, are you using GDM or are you using a different display manager? If you're experiencing the same thing and not using GDM/Ubuntu GNOME, I'll mark the bug as not affecting GDM.

[Jean-Louis Dupond (dupondje)]

I'm using Lightdm, so set gdm bug as invalid.

[Robert Hooker (sarvatt)]

There were absolutely no changes that would cause this in 3.10.0-4 compared to -3 (only 3 patches, one for hyperv, one to enable dynamic debugging, and one adding a pci id for a realtek sd card reader..). Can you attach /var/log/kern.log and /var/log/kern.log.1 that will have historical dmesg info from the failure?

Jul 19 19:07:09 polarimetric-MacBookPro kernel: [ 26.475546] i915: Unknown parameter `modeset'

This seems to be the problem, passing invalid module parameters prevents a module from loading but that is not an invalid parameter so this is the mystery..

[Kelly Hyde (polarimetric)]

Yeah, I thought it was strange because I looked at the changelog for 3.10.0-4 and nothing logically corresponded with this. Since I'm getting "modeset" is an invalid parameter and Jean-Louis is getting that "i915_enable_rc6" is invalid, I'm guessing i915 is completely broken (or modprobe, but I assume that would affect all modules and not just i915).

I've attached the kernel log. All of the relevant boots occurred on July 19 at around 7:00 pm (the error messages that I pasted into the original bug report occurred at Jul 19 19:07:09).

[Robert Hooker (sarvatt)]

So its pretty clear i915 not loading is the problem from that, if you sudo upgrade-initramfs -u -k 3.10.0-3-generic does it break the -3 kernel too? 3.11 allows invalid module parameters instead of preventing the module from loading so whatever is broken here will be "fixed" soon when saucy is updated. I'm at a loss at what is going wrong there though.. Hopefully someone else has more insight into it.

[Robert Hooker (sarvatt)]

update-initramfs I meant there, not upgrade..

[Jean-Louis Dupond (dupondje)]

Ok I did some additional debugging.

update-initramfs -u -k 3.10.0-3-generic:
3.10.0-3 still boots fine, so update-initramfs doesn't break it.

update-initramfs -u -k 3.10.0-4-generic:
Neither does it fix the problem on -4 kernel

boot arguments:
The defaults are:
linux /boot/vmlinuz-3.10.0-4-generic root=UUID=af3a67b1-5cbf-48f1-b0b7-0848ae3017b4 ro quiet splash modeset=1 pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 $vt_handoff

When changing it to:
linux /boot/vmlinuz-3.10.0-4-generic root=UUID=af3a67b1-5cbf-48f1-b0b7-0848ae3017b4 ro quiet splash $vt_handoff
the -4 kernel boots fine ...

What I also noticed it the following error:
[ 23.139890] kvm_intel: Unknown parameter `nested'

This does NOT happen on -3 kernel. So it seems like modprobe or so is broken for -4 kernel?!

[Jean-Louis Dupond (dupondje)]

Booted system.

Kernel -3:
jean-louis@laptop-jl:~$ sudo modprobe kvm_intel nested=1
jean-louis@laptop-jl:~$

=> Works fine, no errors.

Kernel -4:
jean-louis@laptop-jl:~$ sudo modprobe kvm_intel nested=1
ERROR: could not insert 'kvm_intel': Unknown symbol in module, or unknown parameter (see dmesg)
jean-louis@laptop-jl:~$

[ 73.489551] kvm_intel: Unknown parameter `nested'

Modinfo shows it correctly:

Daily build is also fine:

[Kelly Hyde (polarimetric)]

Yeah, my system boots fine with 3.10.0-4 if I remove all of the i915 parameters in GRUB too. Those parameters used to be required to get a working framebuffer on the MBP 8,2 but I guess they aren't anymore.

I'll update the description and title based on the new information.

[Jean-Louis Dupond (dupondje)]

Did rebuild both kernels with pbuilder-dist.

But it remains the same:
3.10.0-4: broken
3.10.0-3: ok

[Andy Whitcroft (apw)]

This was triggered by a SAUCE patch which now has a bad interaction with mainline. Pulled it out until we resolve the issue.

[Haw Loeung (hloeung)]

Hi,

FYI, 3.10.0-5 works fine for me. Thanks.

Not sure if it is the same problem, but:

$ modprobe -l
modprobe: invalid option -- 'l'

$ modprobe --list
modprobe: unrecognized option '--list'

Apparently, modprobe does not recognize the "--list" option.
