Maxtor 250G external disk connected through firewire. The disk is
somewhat suspect, but kernel should not get confused on disk request
timeouts. I do not know certain yet whether this is caused by disk
breaking down, but noises and clicks from the disk are raising
The external disk contains just backups, and accesses to it are rare.
It contains one large BSD filesystem.
There are no other devices connected to the firewire.
The disk was connected with USB1, and worked ok. It also did seem to
work with firewire for about a month, though the use level has been
When using the firewire disk I start getting timeouts. The computer
hangs at some point after this, with rather random effects after
random time, console may continue to work or die, etc.
The log entries look suspiciously like something is getting seriously
wrong in the kernel:

Notice corrupted messages!
The disk is usually hung after first "request timeout" message.
Get a broken maxtor disk ? I can probably ship the disk to someone but
would prefer someone in Finland due to shipping cost and timing (I
want to get it replaced before warranty expires).
When the disk is not used and/or mounted, but is connected to the
firewire bus, the problems do not seem to appear.
