Well - when my box locked up I was also doing a 300MB scp
through my ipw2200 wireless interface. But I did another today
and nothing bad happened.
In another email someone mentioned /var/log/messages - no,
that was totally void of anything peculiar, despite the fact that
I rebooted via Alt-SysRq T / P / S / U / B (this last did reboot
the box). Upon restart however no, nothing in /var/log/messages.
Didn't think it was the case to set up netconsole - only one
occurrence AND with VMWare modules loaded...
I will apply the above fix and will post again in case the hang
issue pops up again. Thanks, ciao,
