Hi everybody!

I connected two USB flash drives and tried to erase them using dd:

dd if=/dev/zero of=/dev/sdc bs=65536
dd if=/dev/zero of=/dev/sdd bs=65536

I left the machine for some hours and found it completely locked
on return. No reaction to the keybard, network access impossible.
A hard reboot was necessary.

Attached find the relevant part of /var/log/messages and the configuration
of the kernel used.

cu,
  Knut
