I have 5 Dell Poweredge 2550 systems. All running RedHat Linux 7.2
with a customized 2.4.7 kernel. Each system has 2 syskonnect Dual
Link Gig ethernet fiber cards. Anyway.. 3 of the systems are older
and have 933M proccessors and are working just fine. On the other 2
they are newer and have 1 Gig processors. I have tried going through
Dell Support and done the normal things.. running all their
diagnostics, I downgraded the bioses in the newer systems to match the
ones that do work.
Basically the problem is, whenever I apply traffic to my gig fiber
nics the system reboots. Sometimes it takes days other times minutes
or seconds. If I run a tcpdump on any interface it almost immediatly
crashes. No messages are written to any logs.
I've tried swapping everything on these systems. Nics, pci slot
caddy, hard drives, memory... Dell recommends I try swapping the 1gig
processors for a 933M which I will try.
I've tried using several different kernels, I've tried using RedHat
8.0 all with the same results.
Oh.. there is also an on-board ethernet adapter: an Intel Corporation
82557 10/100.
I'm associating this issue with the gig cards simply because if they
are out it doesn't seem to happen. But it may take longer for the
effects to show, because I can't generate as much ethernet traffic as
i can gig traffic.
Anybody have any ideas at all of something to try or to look for??
Anything at all?
