Nope, standard lights, and not responsive.

The only thing in the log is
restorecond: Will not restore a file with more than one hard link
(/etc/resolv.conf) Invalid argument
But I'm pretty sure that's irrelevant and to do with the tar command itself.

Tried out the kernel. Unfortunately, it wouldn't boot, gave me this:
Reading all physical volumes...
No volume groups found
Volume group "VolGroup00" not found
Unable to access resume device (/dev/VolGroup00/LogVol01)

followed by a bunch of unable to mount errors.

I've done some more testing, and found that I can trigger the crash  
with an SFTP transfer at high speed ( > 1MB/sec) but not at a lower  
speed (128 KB/sec). I can also trigger it very rapidly just by piping  
a large file over a netcat connection. This leads me to believe it's a  
problem with the ethernet driver  (8139too) under the realtime kernel.

Are there any patches or config options specific to this kernel that  
might be causing it? Should I try the kernel mailing list?
