Well, I haven't been able to reproduce the problem that way. I tried the
following:

$ dd id=/dev/hda of=/dev/null
$ badblocks /dev/hda
$ badblocks -n /dev/hda

...and the same for sda6, sdb, sdc6, sdd, and md2. In each case I killed
the test after several seconds, on the assumption that if the problem
was reproducible within less than a second by triggering a resync, it
wouldn't take long any other way.

If anyone has any suggestions for further tests I can do, I'll be happy
to try them out.

Thanks,
Corey

I noticed you are running a disk on /dev/hda, if this is an older mobo and you use multiple PCI IDE controllers, if they are in certain slots, or you put too many in, they can cause these problems, I have had a few mobos that do it if the PCI cards are in a 'certain combination'-- I have had this happen with an MSI and ABIT board.
