Can you please try 2.6.29 and post full kernel log?
I have posted a boot time dmesg at <http://swm.pp.se/dmesg090416.txt>
Executive summary of everything that follows below (my opinion of what is
happening):
If a drive isn't present at boot time in a slot, it's somehow
"uninitialised". Inserting a drive into a slot not populated before,
doesn't get detected. If I leave the "undetected" drive, and unplug slot 0
drive and insert it again, it's now detected and hotplugging of that drive
works again. I verified this behaviour with slot 2, 3 and 4 below:
So, summary of events (first references the above dmesg file):
At 54s I unplug port1, at 65s I unplug port0, at ~90s I insert same disk
in port0, at around 120s I insert port1, nothing happens, I then remove
port0 again, and re-insert it at ~150 or so.
Since I am a bit uncertain about the times above, I'll do it one more time
and mark each event. State when beginning, both drives are seen.

I put it in port 2 (hm, I'm a bit unsure this is correct, it seems that I
might have done something else here, after inserting into slot 2 drive
isn't visible anyway):

(now I got interrupted by a phone call, but the drive is in port 2, fdisk
doesn't show any sdc drive)
I then unplug port 0:
