I bet you can make your system lock up with the buslogic card just by doing normal non-RAID disk I/O as well. Try copying files between the disks, or something else that's disk intensive. I don't know about special issues with the buslogic card and the kernel you're running. It could be a driver problem, a card problem, or perhaps a wiring problem (this can sometimes kill the kernel because some drivers error-handling suck) or a disk problem (if the reconstruction halts at the exact same place every time this could be likely). -- ................................................................ : [EMAIL PROTECTED] : And I see the elder races, : :.........................: putrid forms of man : : Jakob Østergaard : See him rise and claim the earth, : : OZ9ABN : his downfall is at hand. : :.........................:............{Konkhra}...............: - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
