Machine is running normally for a week or two, then IDE light is lit and processes are stuck in D state (if any disk activity is required -> freezed process). I'm using (ide-) software raid 1 and 5, tested with raid 1 alone and same lockup-problem appears. So, IDE-light is continuously lit but the disks are not reading nor writing. Emergency sync nor the unmount is working. I'm guessing the IDE-code (eh, raid too) might be cause of this. - No OOM situation have been observed, there's been lots of free ram at the time of each lockup. - Processes with no disk activity are not affected (for examples vmstat 1 runs ok if started before lockup) Currently I'm thinking of falling back to .18 with hopes of no more problems. Any similar experiences? Regards, Jarmo PS. An extremely useful feature would be a method to freeze raid resync until fsck is finished. Now, when both are running at the same time server's boot speed is miserable.
