hoping for the best, i make my raidtab, leaving problem drive/bus out (and one other im not ready to put in the array yet) and then do mkraid -f /dev/md0 and get a hard lock, kernel panic. when it dies, the monitor attatched to the dying system spits out some debugging info... disk3, s:0, o:1, n:3, rd:3, us:1, dev:hdp1 unable to handle kernel paging request at virtual address ffffe0b0 printing eip: ... <0> Kernel panic: Aiee, killing interrupt handler! In Interupt handler - not syncing any idea or suggestions are greatly appreciated cheers, ryan __________________________________________________ Do You Yahoo!?
