Hi, I just build a brand new md raid-6 with 5 disks. And on Fedora 12, the auto checking of md devices via a weekly cron job is enabled by default. It performs the checking by echo "check" into /sys/block/mdX/md/sync_action. But after a while, the kernel just crashes, without finishing checking the raid device or leaving anything in the messages file. For now, I've disable the raid-check cron job. The kernel version I'm running is 2.6.31.12-174.2.3.fc12.x86_64.
