Following up on this information I did more testing.

I verified that creating a 2-disk raid-5 and extending it to 3 disks
always works. 3-disk to 4-disk end up corrupted.

BTW I had to change the check in raidreconf for a minimum of raid5
disks from 3 to 2. It worked just fine.

I then moved the first two disks to the motherboard (sd[cd] left on
the TX4). The situation remained the same (but I did get better
performance).

I am now less inclined to blame the TX4 and lean more towards
raidreconf.

I need to create a final test where I hit the disks concurrently
without raidreconf to see how they fair...

I did some tests and so far failed to provoke any i/o error.
