I have a Tyan Tiger S2466 MPX motherboard with Dual Atlon MP 2800+ CPUs and 1GB PC2100 DDR SDRAM. For disk drive I have an LSI53C1030 and 4 Seagate ST336607LWs in a software raid 5 configuration. I installed Centos 4.1 and everything was fine running kernel-smp-2.6.9-11.EL. However when I upated to Centos 4.2 I have run into problems. Namely after a finite amount of disk traffic the system locks completely up. On the monitor console I get message after message from the MPT Fusion SCSI driver mptscsih indicating that there was a failure and that an "ABORT was successful". Unfortunately I don't have the exact message, but I have tracked the problem to kernel-smp-2.6.9-22.0.1.EL. Since I updated from 4.1 I still had the smp-2.6.9-11 kernel around and as long as I boot into kernel-smp-2.6.9-11.EL with all other 4.2 updates installed everything is stable. I can reliably get the mptscsih driver to fail after a few minutes of system uptime (or shorter time if doing disk writes) when booted into kernel-smp-2.6.9-22.0.1.EL.
I checked the Centos archives and did not find anything related to this SCSI card or motherboard. Now before I get lambasted for not having the exact SCSI error message (yes I am willing boot into kernel-smp-2.6.9-22.0.1.EL despite that my raid partition has to be rebuilt afterwards) to get the message. I was wondering if anyone else has had problems with this hardware/driver and/or kernel-smp-2.6.9-22.0.1.EL. If this is a new mptscsih problem I will post more details of my system but I thought I would start with just a general question in case I missed something.
