Hi,
I've a fbsd machine that hangs once in a while, I've this 
en /var/log/messages:
...
Mar  5 14:44:58 chiba kernel: ad2: WARNING - WRITE_DMA UDMA ICRC error 
(retrying request) LBA=2949471
...

So, this means my hd is about to crash?
How can I tell the kernel to reboot on such cases? (via sysctl?)

Thanks
