I'm seeing precisely the same problem. It started with FC3 (didn't have
this problem with FC{1,2}).

Details:

Dell 530n workstation, 2x2GZ Xeon, 1GB memory, On board scsi, adaptec
29160 card, two scsi drives (hosting FC3), one IDE (hosting RH9), a DDS4
scsi tape drive, nVidia GeForce 2 MX. I'm *not* using nVidia's kernel
driver, just the nv userland driver.

I only see the problem when both processors are running (678 smp, 681
smp). Disable the second processor or run the uniprocessor kernel, and I
have no problems.

I observed the following in /var/log/messages just before the hang in
every instance:

Nov 22 19:53:15 fubar netplugd[2355]: eth0: state ACTIVE flags
0x00001043 UP,BROADCAST,RUNNING,MULTICAST -> 0x00001003
UP,BROADCAST,MULTICAST

Nov 22 19:53:15 fubar netplugd[4808]: /etc/netplug.d/netplug eth0 probe

Nov 22 19:53:15 fubar netplugd[2355]: eth0: state PROBING flags
0x00001002 BROADCAST,MULTICAST -> 0x00001043
UP,BROADCAST,RUNNING,MULTICAST Nov 22 19:53:15 lucy-01 netplugd[2355]:

Nov 22 19:53:15 fubar netplugd[4809]: /etc/netplug.d/netplug eth0 in ->
pid 4809

The above netplugd output doesn't happen when running single processor.

When the hang occurs, I've tried to ssh into the box to no avail, and
ctrl-alt-bspace doesn't break out of X. Pinging the box doesn't work
either.

Any suggestions for me to use in further narrowing this down?

Thanks.
