Red Hat Bugzilla – Bug 24610
Kernel panic on echo 1 > /dev/dsp
Last modified: 2007-04-18 12:30:49 EDT
This gives me a kernel panic :
root# /bin/sync # just in case ... oops happens without this too
root# echo 1 >/dev/dsp
< a lot of similar lines , like [<xxxxx>] [<xxxxx>] , snipped >

Aiee,killing interrupt handler
Kernel panic: Attempted to kill the idle task!
In interrupt handler - not syncing
Code: 89 42 04 89 10 b8 01 00 00 00 c7 41 04 00 00 00 00 c7 01 00
When I first encountered this, a lot of random characters was
printed on the screen at high speed, after some ( more than 10 )
seconds it was still scrolling by and I reset the machine.
This happens also if I prelload the sound module.
My /etc/modules.conf :
alias parport_lowlevel parport_pc
alias sound-slot-0 via82cxxx_audio
alias sound-slot-1 es1370
alias usb-controller usb-uhci
options es1370 lineout=1

This defect is considered MUST-FIX for Florence Gold release
what kernel version is this ?
The one from Florence beta2 : kernel-2.4.0-0.43.12
I don't know which architecture ( i386, i586 or i686 ).
But I did a custom install on a Duron 700MHz system,
so it's the one which is normally choosed by anaconda
on such systems.
Could you try with the most recent one? A lot has been changed / fixed since
Same in Fisher.
This time tested without the SB64PCI.
I installed kernel 2.4.2-pre3 ( from Linus )
and the oops does not happen.
There are some changes in the via audio driver
in 2.4.2-preX and also in patch-2.4.1 that probably
fixed the problem.
Probably fixed in our -ac series as well. I'm going to mark this
one fixed RAWHIDE; check later beta releases and if they don't fix
it for you please re-open.
