Subject2.4.10: oops and panic in usb-uhci
From
Date
Hi,

I tried to play a wav on my USB audio speakers (Yamaha YSTMS35D) and got
panic. The oops (processed by ksymoops) is appended. uhci works OK.

Regards, Petr

ksymoops 2.4.3 on i686 2.4.10. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.10/ (default)
-m /boot/System.map-2.4.10 (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.
