Comment 68 for bug 204996

FWIW, I cannot get my machine to lockup.

Tried pushing the CPU by firing off 20+ processes like this:

$ cat /dev/urandom > /dev/null &

All I got was this after about 5 hours:

$ uptime
 21:24:30 up 5:00, 2 users, load average: 25.00, 25.00, 24.83

$ vmstat 1 10

However, this is a headless machine to which I've ssh'ed to run these processes. Dunno if that matters.

Anyone got a suggestion for stress-testing the NIC?
