There are two distinct issues. -- libata locks up in partition table read on an hpt366+old maxtor disk that has ben working fine for many years with old ide driver. (It still works fine when I boot to the alternate ide-based kernel). -- ide driver locks up on hpt366+new maxtor disk under heavy i/o load. I was able to copy 60GB from old to new disk without a problem; however, raid reconstruction locks it up, maybe after 5-15 seconds. This probably is "hardware related"; its something that the new hard drive does. Given that its being sold at a big discount, it may even be that the sellers know that this is a crappy disk. :-) All I want is some way of resetting the disk, and continuing on. I'm stalled in debugging; I'm not sue what I'm looking for. --linas - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
