Well, it has, in the past week, ran memtest86-3a for 12 full passes over the whole gig of ram with no errors. This was the longest test, I gave it a 2 hour, 5 pass test before I ever booted linux the first time on this motherboard over 2 weeks ago now, a new Biostar M7NCD-Pro, with an nforce2(3?) chipset. I did that because I was comeing from an older board whose memory had been overstressed by a failing video card and I wanted to make sure this new memory, nearly $210 worth of it, was good. I gave it another, probably 4 hour test after the first couple of crashes, which it also passed. And it got worse as the kernel versions incremented from 2.6.7. I can have the same fault in prune_dcache() while running a 2.6.7 kernel without an instant lockup, but it will eventually die, maybe half an hour later. Move to 2.6.7-mm1, which has a patch to fs/dcache.c that remains untouched thru 2.6.8-rc2, and those kernels, if they lock up, do it totally, often with nothing in the logs at all. That was the case today, on 2.6.8-rc3, which has a new dcache.c patch in it if I read the release notes correctly.
If this is dodgy hardware, give me something to take to tcwo.com when I ask for an rma. Not having M$ windows of any kind here, I frankly haven't had the inclination to look at the cd's that came with the board. Should I?
Or does linux have a hardware test suite I've not heard about?
