Hi, [using kernel 2.6.23 and mdadm 2.6.3+20070929] I have a rather flaky sata controller with which I am trying to resync a raid5 array. It usually starts failing after 40% of the resync is done. Short of changing the controller (which I will do later this week), is there a way to have mdmadm resume the resync where it left at reboot time? Here is the error I am seeing in the syslog. Can this actually be a disk error?

I've seen something similiar, it turned out to be a bad disk. I've also seen it when the cable was loose.
