after the crash we switched back to USB 2.0.
Finally the system seems to be stable now. The problem was probably
related to syslogging. After upgrading syslog-ng the server remained
responsive up to now. However, it was a strange effect as it occured
most of the time after accessing the USB drive. Maybe one of the kernel
messages when attaching/mounting the disk caused it. In all cases
pressing SysRq+h "unlocked" the system.
Ciao,
