What else is running? What's mounted? I ask, because I can remember some problems with heavy IO... - on mounted ext2fs filesystems - on nullfs-based mounts (doesn't apply to 3.9, of course) - with large writes to external el-cheapo disks attached to USB, allthough this tends to toast the disk, not the system Ciao, Kili ps: as somebody else wrote, fishy power supplies are a common (and hard to debug) cause of failure, too.
