I would gladly do so, only... I can't seem to make the bug reappear. I booted 2.6.20-mm1 again to get the extra info, and thought I would try plugging in devices one by one to see what was causing the problem, but I cannot get it to come back. This is odd, considering it happened at least 5 times in a row when I was gathering the logs for the first bug report. I would attach /proc/bus/usb/devices, but /proc/bus/usb is an empty directory? And, no I'm not using any modem at all. No cellphone either. A scanner, a PS2 port, a mouse, a compact flash reader.. I'll try that patch and let you know if it reappears. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
