** Description changed: My system persistently crashes with a kernel panic during a copy between hard disks evident by complete lock-up of the screen, flashing keyboard LED's and a kernel panic dump to CLI on tty1 I have proven the crash does not occur using other Linux distributions on the same system, only with Ubuntu 8.04. The same system copied >250GB data using a Knoppix boot CD successfully. After some investigation I've discovered the following facts about the crash: -Can occur randomly from immediately starting the copy operation but more often after between 800-1500MB copied -Copying same data into smaller chunks i.e. one file at a time can prevent crash in some (but not all) cases -Occurs between disks, copy from/to the same disk is unaffected -Occurs between disks on the same controller and on different controllers -Occurs between disks on normal PATA controller and SATA and between SATA controllers -Does not seem to matter which controller or combination of controllers is used for copy function -Occurs using nautilus copy function and bash 'cp' command but 'cp' seems to work for longer before crash -Seems to be more prone to crash while multiple disk i/o functions are active e.g. playing music, browsing web etc + -Using linux-386 instead of linux-generic allows much more data to be copied before the crash System information Linux monster 2.6.24-19-generic #1 SMP Wed Aug 20 22:56:21 UTC 2008 i686 GNU/Linux Hardware: AMD Athlon XP 3000+ Asus A7V8X w/ onboard promise SATA RAID Maxtor Promise 2-port SATA 150 PCI card 4x SATA hard disks + 1 PATA hard disk (now removed) 1.5GB RAM in 3x512MB configuration, reported clean of error by memtest86. No evidence in logs to provide any additional information that I can find.
