>Description:
The system freeze on network activity.
Tried with alt+f1 and ctrl+alt+canc, no response, only way is to hard poweroff the machine.

Hardware:
This system is freshinstalled on Toshiba R200 machine, I have another Toshiba R200 with FreeBSD 8.2 i386, on that machine there isn't the problem.

Lan Driver: msk

I tried with knoppix to test LAN nic, but no problem after 4 hours of heavy network traffic.

>How-To-Repeat:
This problem always occur when I try to portsnap fetch, or pkg_add -r nano.
