Re: Disk I/O & Lockups

Well I've seen instances on my box, where I try to SSH into it from my 
laptop running SecureCRT and I either get a message saying the SSH service 
is not being provided or provided on a different port, or it prompts for 
my login which I enter, then it just hangs there and I never get a prompt 
- just a blinking cursor. For some strange reason, if I bounce the box, 
SSH will function again. As this just started happening (after some 
hardware upgrades) specifically new memory, new processor and additional 
hard drive.

I haven't had time to diagnose what the problem is yet though...

        Subject:        Disk I/O & Lockups

Has anyone experienced, with any recent version of RedHat, frequent
system lockups (total, no SSH or anything) during low-moderate levels of
disk activity? I have a ABIT KT7-RAID motherboard and am really
beginning to blame this on the motherboard/chipset. I have 4 IDE
controllers and make use of all of them (2CDs, 3HD) on a regular basis,
and it happens only (as far as I have noticed) with the hard drives.

I'm not real sure what I should be looking for in logs if anything has
been logged at all. Any ideas?

I'm also getting this from my USB controller at an alarming rate:
kernel: usb-uhci.c: interrupt, status 28, frame# 1418
kernel: usb-uhci.c: Host controller halted, trying to restart.

I intend to replace this motherboard as soon as possible, but am curious
if these problems are solvable. Thanks in advance.
