I didn't have problems with rhel ws3 or with the kernel it came with.
I removed it in favour of debian a long time back, when debian/etch r0
was released.

I have been running debian etch r2 (4.0 r2) ever since, which comes
with kernel (2.6.18-5-686). As you might notice from the mentioned
kernel versions, I tried upgrading to kernels from lenny/debian and
sid/debian hoping to find a solution. I tried from 2.3.13 - 2.6.25
from both debian packages and vanilla sources (as they are called),
but the problem persists. It started and is continuing on debian.

I have 2 ISPs hooked into this box. One is CIR, the other is ADSL. The
ADSL runs over pppoe. I don't know if the 2.4.x kernels support pppoe.
The 2.6.x kernels do. I need to run 2 ISPs on this box seemlessly.

The last rhel version I used was using kernel 2.6.9. I'm going to grab
that and see if that helps.

I need pppoe, iptables, vpn, scsi with raid support, smp, and a around
8000 file descriptors to run stable on this box.
