Greetings,
We have a SuperMicro X5DP8-G2 Motherboard, 2xXEON 2.4, 1GB RAM server running 5.4-STABLE that keeps freezing up. We have replaced RAM, HD, SCSI controller, etc. To no avail. We are running SMP GENERIC Kernel. I cannot get the system to panic, leave a core dump, etc. It just always freezes. The server functions as a web server in a HSphere Cluster. I am about out of options besides loading 4.11 (since our 4 series servers never die). Any help, feedback, clues, similar experiences, etc would be greatly appreciated.
On SCSI: The onboard Adaptec 7902 gives a dump on bootup but appears to work. I read the archived post about this issue. The system still locked up with an Adaptec 7982B that did not give this message.

We had many issues with Seagate drives and and S/M boards with the onboard Adaptec scsi controllers. Seagate offered no help other than to suggest putting in a network card (in lieu of the onboard) and/or disabling SMP; neither solution was acceptable so we switched to IBM/Hitachi drives and the problems disappeared. By the way, the problems manifested themselves in those servers where we had more than just one hard drive installed. This was even after updating to the latest firmware etc; Seagate insists no problem with their drives although other drives work perfectly well. YMMV
I do see you say you tried other harddrives .. which ones did you use?
