I just updated the alsa-driver from cvs today and I'm using a stock
2.4.18 kernel on my laptop which is an older Pentium MMX system.
The only option I gave cvscompile was --with-cards= for the opl cards.
modprobe snd-opl3sa2 port=0x370 wss_port=0x530 fm_port=0x388 midi_port=0x330 irq=5
dma1=1 dma2=0
After three reboots I have determined that it doesn't crash just on
processes accessing the sound card it crashes randomly on any process.
I would manually load the module, on the oops I captured I ran
alsamixer which is the process that oopsed, copied /proc/ksyms, dmesg,
and rebooted as the last time I tried to decode the oops without
rebooting ksymoops was unable to run due to crashes.
ksymoops 2.4.8 on i586 2.4.18. Options used
-V (default)
-k alsa_oops3_ksyms (specified)
-L (specified)
-O (specified)
-m /boot/kernel/2.4.18.map (specified)
Intel Pentium with F0 0F bug - workaround enabled.
