[Bug 1297659] Re: Unknown IRQ result on Lenovo T400

 

Crazy, after upgrade, dist-upgrade, I'm still on 3.14 kernel.

But after restart and trying using command

watch /proc/interrupts
 49:        145        143   PCI-MSI-edge      snd_hda_intel

and playing audacious, mute-unmute etc...

show normally without errors or weird characterst instead snd_hda_intel.

uname -a
Linux skymond 3.13.0-19-generic #40-Ubuntu SMP Mon Mar 24 02:37:00 UTC 2014 i686 i686 i686 GNU/Linux

I think now is ok but I'm not sure how and why. Think to mark it solved,
if repates errors maybe to context reopen this ticket?

** Changed in: linux (Ubuntu)
       Status: Incomplete => Confirmed

Title:
  Unknown IRQ result on Lenovo T400

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Using cat /proc/interrupts it will show unknown data of IRQ, but I
  think it's on kernel bug or Ubuntu won't parse as well, I'm not sure.

  Image sample show under IRQ number 49 PCI-MSI edge but I can't
  recognize what depends on and maybe is a bug?

  This bug didn't affects on critical errors and not crashes on
  firmware, drivers, etc...

  MOD: Please move from "mousepad" category to kernel or proprietary category.
