2.5.8 OOPS usb-uhci

PIII 650 UP. kernel tainted by speedtch.o (usb Speedtouch Alcatel driver). OOPS logged in /var/log/messages during shutdown (the 2 oops come together). *It is not repeatable*. I haven't catched such oops with 2.5.8-pre3.

I hope it can help.

ksymoops 2.4.5 on i686 2.5.8. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.8/ (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.

Bleah, please send any problems with this driver to the authors of the driver, as I have no idea of what that driver does (or even if it has been properly converted to the 2.5 USB api changes.)

thanks,

greg k-h

This speedtouch kernel mode driver has problems with preemption. Perhaps this is the source of your problem. This is one reason I moved to the user space driver, see http://speedtouch.sourceforge.net
