I was hoping that the recent flurry of fixes in the ac97 modules would
fix my problem [Oops on my Sony Viao Z505S laptop with snd-nm256].
They haven't, but at least I seem not to freeze. Here's the latest
ksymoops output. [I just finished running CVS and rebuilding in all
alsa-* directories].
David
----------------
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
Unable to handle kernel NULL pointer dereference at virtual address 00000000
