I have a brand new poweredge 2900 with 10 SAS drives configured in two arrays via the built-in PERC 5 raid controller as:
raid 1: 2x73GB
raid 10: 8x300GB
It's got 4GB of ram, and it's intended to be an NFS filestore.
For some strange reason, logging in with ssh works great, it returns a prompt, all seems well.
I go to run a simple command like 'top' or 'yum -y install <package>', and my xterm/ssh session just locks. In some cases, it's drawn half of the top screen and hung, in other cases, it doesn't even do that. Kill the xterm window, bring a new one up, right back in, try it again, it repeats.
What's interesting to me is that I have all kinds of other 'lesser' systems running CentOS 4.4, and I have none of these issues with them. My ~1.1TB raid 10 drive is sliced up into 4 parts, with the big one being about 950GB. Near as I can figure, I haven't hit any limitations, but I'm stumped by something that I *think* is probably either relatively trivial, or just a straight out hardware incompatibility. One thought is that it could be related to the Gb ethernet devices (bge).
Commands like 'ifconfig -a' work great. 'dmesg | grep eth0' locks up the session.
This is relatively frustrating. Googling doesn't seem to net any real results, and I can't seem to find anything relevant in the logs.
One more relevant bit to add, this behavior does not exist from the console.

Hi,
Have you tried booting with the non-smp kernel to see it the same problem occurs?
If you have an Intel nic handy you could try to see if that eliminates the problem. I recently had trouble with the sky2 module, but in that case, I would loose all network connectivity until the module was reloaded. I have now had no problems since switching to the Intel nic.
Hope that helps.
A.
