@steubens: ok, scsi plus block fix from comment #36 should be needed (without one or another you can hit problems at different locations), but on the trace it seems you're not reaching the conditions that they fix. At least I think you need one more fix, I built a kernel with the probable fix, but first as a sanity check, please test the kernel at:
It contains the previous fix plus the block fix I requested you to test on comment #36, but you still should see the oops with it. Then please test next kernel at:

The r4 kernel contains an additional fix I made which should address the problem shown on the last stack trace you posted, let me know your results.
