Oops in latest CVS on Sony Viao Notebook (nm236)

Oops in latest CVS on Sony Viao Notebook (nm236)

[David Ronis]

I've reported this before and the latest CVS still has the problem.
I'm running linux-2.4.22 on a sony Z505S laptop.  Alsa used to run
(CVS versions) on earlier versions of the kernel (at least up to
2.4.19), but hasn't worked on the latest.  I have both the preemptive
and lowlatency patches installed.


Usually what happens is I lock up, but occasionally I get to see an
oops on the screen, and even more infrequenty, am still running.  This
happened yesterday.  I did a build/install of the current CVS and then
ran aplay. Here's what ksymoops reports:

ksymoops 2.4.9 on i686 2.4.22.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.22/ (default)
     -m /usr/src/linux/System.map (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.

Warning (compare_maps): ksyms_base symbol IO_APIC_get_PCI_irq_vector_R__ver_IO_APIC_get_PCI_irq_vector not found in System.map.  Ignoring ksyms_base entry

Here's how my kernel's sound section is configured:

CONFIG_SOUND=m
CONFIG_SOUND_OSS=m
CONFIG_SOUND_TRACEINIT=y
CONFIG_SOUND_VMIDI=m
CONFIG_SOUND_NM256=m

everything else is not set.

did you update both alsa-driver and alsa-kernel trees?
