Problems (lockup/hang) with PCI-X slot on X5DPL motherboard

Problems (lockup/hang) with PCI-X slot on X5DPL motherboard

[Orion Poplawski]

I'm getting to my wits end, so any help would be greatly appreciated.

I've got two disk servers, on with SuperMicro X5DPL-iGM motherboard, the 
other with a X5DPL-TGM board.  These system use the E7501 chipset, and 
provide to PCI-X buses.  One for slots 4 and 5, the other for slot 6 and 
the embedded Intel 82545EM GigE NIC.

I have had nothing but trouble trying to use slot 6 on these machines. 
Recently I've been trying with a MV88SX6081 133MHz PCI-X card.  In both 
machines I get lockups when trying to use the controller.  I also see 
corruption on the on-board NIC on the TGM (though not on the iGM) with 
the card in slot 6.

I'm running Fedora Core 4 with kernel 2.6.12-1.1456_FC4smp and mv_sata 
driver 3.6.1.  I'm stuck on the older kernel because of the mv_sata driver.

Now, maybe this is all the fault of the mv_sata driver, but I believe I 
had problems on the iGM machine with a Intel 82545GM PCI-X nic in slot 6 
as well which does not use the mv_sata driver at all normally.

Thoughts?

Is there a way to find out bus speed for other slots/cards?

In general, yes, though I just had a lockup with this new MV card in my 
test system.  Otherwise, my X5DPL-TGM with on MV card in slot 4 and one 
Intel GigE in slot 5 has been quite stable.

I think it's only related to device/bus issues, not in general.


Thanks a lot for the reply.  I'll be trying to turn down the bus speed 
in the BIOS to see if that help.
