lufthansen 0 Report post Posted November 8, 2007 This error is always due to data corruption. Mostly RAM, but in your case seems to be PCI or RAID adapter. You're right. I'm amazed! After running all kinds of memory tests, none of them reported any errors. The system ran fine for 4 months, then started to act up again. Did reinstall, ended up with the same problem (same files always reported missing or corrupt, cyyicons one of them). Replaced the seemingly ok mem chips, and presto! Now everything runs smooth, reinstall a dream and I'm running a week of benchtesting of the raid 5 while crossing my fingers. I actually think I nailed it this time.... Still puzzled that none of the memtests picked up any errors though. Did 72 hours of continous testing - nothing! Share this post Link to post Share on other sites
