No syncing after crash. Is this a software raid bug?

[Kasper Dupont <78331655489368831086@expires.02.sep.2006.kasperd.net>]

I have a FC4 installation (upgraded from FC3) using kernel
version 2.6.15-1.1831_FC4. I see some symptoms in the software
raid, which I'm not quite happy about.

After an unclean shutdown caused by a crash or power failure,
it does not resync the md devices. I have tried comparing the
contents of the two mirrors for each of the md devices. And I
found that on the swap device, there were differences.

Isn't this a bug in the software raid? Shouldn't it always
resync after reboot, if there could possibly be any difference
between the contents on the two disks?

I know that as long as only swap is affected, it is not going
to cause data loss. But how can I be sure it is not going to
happen on file systems as well?

Should I report this as a bug in Fedora Core or did I miss
something?
