Bug#308389: kernel-image-2.6.8-2-k7: using USB flash drive causes death of kernel USB system, sometimes
Package: kernel-image-2.6.8-2-k7
Version: 2.6.8-13
Severity: normal
When connecting my USB flash drive to my machine, sometimes it will
cause the whole kernel USB system to lock up. After this, anything
trying to access the files in /proc/bus/usb freezes in the kernel, and
further USB events are ignored until a reboot. The freeze happens maybe
once every 3 or 4 times I plug it in, or so.
When the device is plugged in and things go bad, this is what shows in
/var/log/messages:

...and nothing more ever happens with the USB system after that until
the next reboot. For the sake of comparison, this is what a 'proper'
connection of the USB device produces (everything just the same except
it works this time):
