Yes. I just tried alsa 9.2, 9.4, 9.5 and cvs all with 2.4.22-pre6
I'm running:
arecord -D imic --rate 44100 -f S16_LE - | aplay -
and then press ^C
I have gotten sound from this thing at one point. If I run arecord with
the -d <delay> and let it exit by itself it does not oops!!!!!
0.9.2 gives an error immediately, something about invalid sync pipe.
No oops but also no sound.
Others seem to give the same oops (always BUG in spinlock.h anyway) and then a hard
lockup.
>From my handwritten notes:
BUG ...include/asm/spinlock.h:86
process: aplay
I type in the backtrace by hand to ksymoops (this for alsa-cvs):

I get some warnings from ksymoops so here is the full output FYI:
[EMAIL PROTECTED]:/root # ksymoops<oops
ksymoops 2.4.0 on i686 2.4.22-pre6. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.22-pre6/ (default)
-m /boot/System.map-2.4.22-pre6 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
