RHEL 5 + Tyan Server Board + X Windows = Lockup
Hi All,
I'm at a loss to explain or correct a problem I am seeing across two DIFFERENT (and, admittedly, dated) Tyan Server Boards.
The boards are the S2460 and the S2466-4M motherboards. I use these boards in a compute cluster - for about the last 5 years now.
I recently shut the cluster down to upgrade to RHEL 5 across all machines in the cluster. We were running a mix of RHEL 3,4,5.
After upgrading the two head nodes to RHEL 5, I noticed that after a certain amount of variable time, the mouse would simply freeze while in X (run level 5). The amount of time varies drastically. Sometimes it's just when starting X, sometimes it takes 8 hours, but it eventually locks up, no log messages, nothing.
What I have tried to do so far to correct this is to use the old stand-by kernel options "noapic, nolapic, acpi=off" - this does not help.
I've also tried changing out the mouse between USB and PS/2 - no help
I've also switched from an NVidia chip AGP board to an ATI AGP board - no help.
A long time ago, back when we were running Red Hat 9 on this thing, the kernel option noapic did the trick like magic - Now, I'm wondering why that seemingly has no effect.
Just to fill in details, these boards are Tyan S2460 and S2466-4M, they have dual AMD-MP CPUs and 2 GB each.
Their peripherals are quite different from each other so I do not think it is something with an odd driver.
If anyone has any pointers or clues to this matter, I would love to hear them!
Thanks,
Phil
