Unfortunately this means that no useful information was captured.

I also have another crash dump on that system. Hope it will be more useful.

Replacing Net=
Mos by MOXA multiport card also changes nothing. But recompiling kernel wit=
hout SMP changed time between panics from 6-12 hours to 1-1,5 weeks. But pa=
nic still occurs with

and corrupted stack. So, seems that problem is not in sio.
