Folks,
Attached is the output of ksymoops that I am receiving when I load either uhci
or usb-uhci. This with kernel 2.3.99pre9-2 (with latest patches).
No one has come back with any ideas on this, so I have cross posted to the
kernel development list and the usb list.
Sorry the ksymoops output is not better, but I could not run it with the uhci
or usb-uchi module loaded for obvious reasons (system crashes!)
Hope this is some help in finding out why this is happening.
syslog also attached (relevant parts).
Thanks for looking at this (if you do!)....
Alan.
ksymoops 2.3.4 on i586 2.3.99-pre9. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.3.99-pre9/ (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.
