Hi, We are currently deploying Tyan S2882 Dual Opteron Boards, and we have found the system to be quite unstable. After BIOS updates and kernel changes we still get random kernel panics when under load.
Anyone has these boards and has found any solution, as I have mailed other users of this board who also reported random kernel panics and an unusual number of hardware problems. So far we have solved the - broken BIOS problem with an update to the most recent BIOS. - Discovered that some power supplies can produce problems http://www.anandtech.com/mb/showdoc.aspx?i=2608 - FS corruption due to a firmeware problem in a RAID hardware board - MCE chipkill errors (non-fatal) due to apparent bad RAM To be solved: - random kernel panics that take out the logging even when all debug flags are set in the kernel, as it fails to sync the disc during the kernel panic. _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
