It was probably a defect motherboard (the only thing that I could reproduce was a corrupting DIMM socketbut by not using it the system reliability only improved up to a certain level, replacing motherboard CPU and memory seems to have fixed my reliability issues, so my guess is that my motherboard has been failing slowly)
OTOH one thing that I noticed that debugging my issues involved quite a bit of scripting. I'd guess having a tool that verifies basic hardware soundness would be great. In my case the debugging invoked creating urandom copied files recording MD5 sums, and repeats of reading and testing them, which suggested to me that multiple components were data corrupting; the bad DIMM socket I've found via manually testing with memtester86) Andreas Am 30.03.2012 12:01 schrieb "Christopher M.
