do you have an em or bge ethernet?
Yes. I do have an em0. My em0 does not share irq with other
device. I got watchdog timeout message every few days, but
I didn't get any in the deadlock above since boot.
I have a box on which I had to replace the onboard bge with a 3com
card since there was some interference between the bge and file
system drivers causing total lockups during network use combined with
heavy disk use. It was 100% reproducible by doing a level 0 dump on
the nfs exported volume. My symptom was that the FFS would lockup
that volume. If I got lucky, it would lock up the whole system and
the only way out was via console debugger.
