Hyperthreading may not be the issue in this case. I had a Dell PE6600 that would lock hard, no network, no log file entries, no console response and the issue was the NIC kernel module. Check out these threads:

When Dell ships Red Hat preinstalled they use the bcm5700 module. I switched to that module and haven't had a lock since and we have Hyperthreading enabled. If you wish to try the bcm5700 module, edit /etc/modules.conf and replace: alias ethX tg3 with: alias ethX bcm5700 Then at the console (not remotely) do the following: service network stop rmmod tg3 service network start That should get you up and running with the bcm5700 kernel module and it should remedy you issue. The tg3 driver is better from what I've heard, so if you wish you can try these __UNOFFICIAL__ kernel RPMS posted by a one of the tg3 developers to the Dell Linux PowerEdge mailing list: http://people.redhat.com/jgarzik/tg3/tg3-1.2/rpms/ Please read the threads listed above and remember these are UNOFFICIAL. I've been running with 2.4.18-17.7.xbigmem and the bcm5700 driver for weeks now with no issues. Hope this helps, Andy. -----Original Message----- From: Rick Johnson [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 04, 2002 1:35 PM To: [EMAIL PROTECTED] Subject: Re: RedHat 8.0 SMP kernel system freeze -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [EMAIL PROTECTED] wrote: | | Just installed two new Dell PowerEdge 2650 servers: dual Intel Xeon 2.0 | GHz processors, 5x drive SCSI RAID (5).
