Hi all,
When I unplug my usb mouse and keyboard for longer than a few seconds
(not sure of the exact time, but must be more than, say, 5 seconds) I
get a BUG message in dmesg. When I plug them back in, they don't work!
I just tried to unload & reload usb-hid, but modprobe locked up on the
reload. It appears the only way to fix it is to reboot.
This happens with tuxonice sources 2.6.23-r9 but never happened with
2.6.22.* or earlier.
Here's the dmesg output:
usb 3-2: USB disconnect, address 5
usb 2-1: USB disconnect, address 4
BUG: unable to handle kernel paging request at virtual address 00100100
printing eip:

Strange as it sounds, I haven't had much experience with these- where do
I start looking?
thanks,
