Hi Folks,

SL4 works great on all of the Dell Optiplex GX280's I've tried it on. 
However, I'm having some rather mysterious behavior on a dell poweredge 
750.  Dell has said they will start certifying hardware and officially 
supporting the vendor's enterprise 4 operating system next month, so it 
may not be worth the effort to try to figure this out.  Anyhow, I 
thought I'd sent to the list and see if anybody else is having any 
issues like this.

1.  Sometimes, processes just seem to hang.  I've noticed this over an 
SSH session, a lot of times when using the yum command.  I ssh in to the 
server and see the process still in the process table.

2.  Doing a 'service iptables restart', the system stalls on the 
"Unloading iptables modules:".  If I go to a different window and ping 
the server, the iptables service restart resumes.

These issues aren't sounding like userland issues to me, although they 
very well could be.  Here are the kernel modules the machine is using:
