[Kernel-packages] [Bug 1301490] Re: "PRIME Profiles" option no longer available in Nvidia Settings

[Alin Andrei]

I've managed to fix this by blacklisting nouveau:

$ cat /etc/modprobe.d/blacklist-nouveau.conf
blacklist nouveau
blacklist lbm-nouveau
alias nouveau off
alias lbm-nouveau off

[Kernel-packages] [Bug 1269404] Re: BUG: soft lockup - CPU#2 stuck for 22s! [systemd-udevd:546]

[Alin Andrei]

I forgot something: those errors occur when switching to a tty AFTER
logging in to Unity. If I get to the login screen and then I switch to a
tty, the laptop doesn't freeze when switching to the tty and no errors
are displayed in the tty. Maybe that's somehow relevant.

I investigated further and something is really messed up with this last
kernel. Every time I switch to a tty, the laptop freezes and the tty
displays a huge list of error messages. And this happens even without
"threadirqs". I'm attaching photos  of the errors.

Well, I spoke too soon.

With this kernel, the laptop doesn't freeze on boot. But the laptop
freezes when I click the restart button under Unity, it happened every
time. It doesn't occur with the "sudo reboot" command though.

Bug description:
  I'm using Ubuntu 14.04 Trusty Tahr 64 bit and my laptop (Dell XPS
  L702x using Nvidia Optimus) can't boot starting with kernel  3.13
  (I've tried all three updates: 3.13.0-1-generic, 3.13.0-2-generic and
  3.13.0-3-generic). When booting, I get this error: "BUG: soft lockup -
  CPU#2 stuck for 22s! [systemd-udevd:546]"

  Booting the old 3.12 (3.12.0-8-generic) kernel works.

  Here's the relevant part from syslog:

[Kernel-packages] [Bug 1269404] Re: BUG: soft lockup - CPU#2 stuck for 22s! [systemd-udevd:546]

[Alin Andrei]

I found out what was causing it: starting with v3.13-rc1, having
"threadirqs" under "GRUB_CMDLINE_LINUX_DEFAULT" in the /etc/default/grub
configuration file causes the behaviour I mentioned above.

After removing "threadirqs" from /etc/default/grub, the bug doesn't
occur any more. I guess this is still a bug in the kernel, right?
Because Linux 3.12.0-8 from the Ubuntu repositories works with
"threadirqs"...

  I'm using Ubuntu 14.04 Trusty Tahr 64 bit and my laptop (Dell XPS

Thanks!

Unfortunately v3.13-rc8 doesn't work either...

Both v3.13-rc2 and v3.13-rc1 didn't work. This time I was able to make
photos of the errors. I've attached 2 photos to the bug report...

  I'm using Ubuntu 14.04 Trusty Tahr 64 bit and my laptop (Dell XPS
  L702x using Nvidia Optimus) can't boot starting with kernel  3.13
  (I've tried all three updates: 3.13.0-1-generic, 3.13.0-2-generic and
  3.13.0-3-generic). When booting, I get this error: "BUG: soft lockup -

  Booting the old 3.12 (3.12.0-8-generic) kernel works.

[Kernel-packages] [Bug 1269404] Re: BUG: soft lockup - CPU#2 stuck for 22s! [systemd-udevd:546]

[Alin Andrei]

I've tried the kernels you mentioned and:

- v3.12 final worked
- v3.13-rc3 didn't work

The problem is that the bug behavior changed after a couple of reboots.
I was trying to take a photo of the error messages but I couldn't get a
clear photo and after a few reboots, the error wasn't displayed anymore
and the laptop booted until the login screen (LightDM), then it freezes.
Once I was able to log in to the Unity desktop and only then the laptop
froze.

So basically now the laptop freezes when the login screen shows up when
using  v3.13-rc3 as well as when using the initial kernels that caused
issues (3.13.0-1-generic, 3.13.0-2-generic and 3.13.0-3-generic).

Unfortunately, that means I couldn't take a photo of the old error but
I'm attaching the syslog, maybe you can find something helpful there.
Let me know how else I can help...

Hello,

The last working kernel was 3.12.0-8-generic and the first for which the
bug started was 3.13.0-1-generic. I'll also try what you said and post
the results.

Bug description:
  I'm using Ubuntu 14.04 Trusty Tahr 64 bit and my laptop (Dell XPS
  L702x using Nvidia Optimus) can't boot starting with kernel  3.13
  (I've tried all three updates: 3.13.0-1-generic, 3.13.0-2-generic and
  3.13.0-3-generic). When booting, I get this error: "BUG: soft lockup -
  CPU#2 stuck for 22s! [systemd-udevd:546]"

  Booting the old 3.12 (3.12.0-8-generic) kernel works.

  Here's the relevant part from syslog:
