I moved a 32MB 168 SDRAM from another machine to my SuSE 5.1 machine.
POST reports that everything is OK with the Memory with each Power ON or C-A-D.
Since putting this DIMM I have experienced random 'segmentation fault' and 'core dump' two times today. First time it was during shutdown of routing whilst shutting down and the second time it was from SMB servers whilst booting up. The 'seg. fault' did not lock up the machine and in each instance the subsequent shutdown/boot up processes completed successfully. On subsequent shutdown and reboot things were OK.
Interestingly enough, when I had this DIMM in a Win95 machine it would cause random lock up of the machine and I would have to reset the machine.
Can a memory chip be flaky, yet pass POST tests and subsequently be the cause for segmentation fault? Is there any way to test out the DIMM besides the POST?
Any comments from those who have experienced similar symptoms?
Hmm, did you enable the Memory test in the BIOS? Most BIOSes have a "quick boot" option, which does not do any tests at all. You can determine this from the speed of the memory counting process on startup. If these numbers just fly by, the memory checking is probably disabled. The best memory test is a repeated kernel compile.
