I just grabbed Arjan's last kernel

Linux planck.colorado.edu 2.6.6-1.421smp

Same usb mess.  The problem is completely reproducible:  a large rsync to a 
usb 2.0 flash disk will eventually trigger this message in the kernel:

Jun  3 18:09:53 planck kernel: usb 1-6: control timeout on ep0in
Jun  3 18:09:53 planck kernel: scsi: Device offlined - not ready after error
recovery: host 3 channel 0 id 0 lun 0

Once this happens, there's no recovering, of course.

Many others are reporting similar usb-storage problems, with the same 'control 
timeout on ep0in' message.  Smells to me like a kernel bug, though I could be 
wrong.

Still confirmed with the new kernel.  I'll try with a few acpi=something 
options and see what happens.

Thanks for the help,
