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.

Thanks,

DS
