To be honest, I haven't tried to reproduce the problem. I got these
messages about every two minutes while resync'ing md0, which took well
over 24h (perhaps 28-32h) for about 2.9TB.

Depending upon what the distributor says in the new year, I may need to
rebuild the raid and install debian. And I will definitely keep you in

I have done a 'smartctl -t long /dev/sd[a-d]' w/o any errors. So I
believe the drives are o.k. Just the messages about checksums as in the
files I had attached are getting rather annoying.

Unfortunately, I do no longer possess the original dmesg output. If you
like, I could attach an entire '/var/log/messages' w/ rotated logs.
