Kernel 2.6.10 and later issues with USB

[Matt Patterson]

Perhaps you are experiencing the inotify bug. This is a freeze in the 
kernel when it gets notified of a newly inserted device. I believe the 
kernel boot option was "noinotify". I thought that was my problem for a 
while, but pinned it squarely on the pci vid card in the end.

Also, try running a non smp kernel and see if you can reproduce your 
problem, if you cant then you have one more clue and can mess around 
with the smp options in hte bios.
