watchdog timeout

[Riccardo Veraldi]

it is 9.1-RELEASE

FreeBSD blade.infn.eu 9.1-RELEASE-p3 FreeBSD 9.1-RELEASE-p3 #0 r251822:

I never saw this message and I am using FreeBSD on sparc64 since the 
first release was available.

I have no way to reproduce it, because it appeared suddently without any 
specific cause.
The system was not under heavy load, I Was not compiling anything...

But I had other errors recently  which are really not related I think, 
mainly parity SCSI errors on isp0

but it never occurred again.

BTW the system is working like a charm after these errors and i had not 
any downtime.

The machine anyway is quite old I think it is from 1999 and I upgraded 
it to dual 1200MHz CPU

thank you for ur help
