Argh, died again!! It had been stable for over 12 days. Same error message, and the root md is degraded and dirty just like last time. This is a very severe state with high risk of data loss. When things went sour, terminals and most applications still kept working, but anything that touched the filesystem froze up. I had a shell open in a chroot on a ramdisk, but dmesg just hung for a few minutes and then exited with a "Bus error". I had no other way of examining the kernel log since the machine runs X.
This was running 2.6.15-rc4. Crashes seem to happen less frequently with it than with 2.6.14.x, but when they happen they leave the RAID in a severe state. I also don't think 2.6.14.2 said anything about disabling the IRQ.
I'm very desperate now. About every week I experience a crash that damages my RAID array to the point where it can't boot, as if the instability wasn't bad enough. Do I need to buy a hardware RAID card? - 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/
