Which non-AS RH8.0 kernel should one use to not get hangs from tg3?
I had to downgrade our Dell PE2650 from 2.4.18-24 to 2.4.18-17 since
2.4.18-24 and -19 caused bi-weekly hangs, while -17 and earlier never
had any problems. -18 seemed Ok, but the box didn't run it very long.

This is a compile server with very light network load: a couple of
ssh sessions, NFS-mounted home dirs, ntpd, nothing else.
