What would be the best approach?
- if the kernel boots, it's obviously 'good'

then? If it doesn't work with your patch, would it be 'bad' then?
A few reboots later...
As you said, during my bisecting, at a certain moment I needed your
patch (I booted, got a problem, patched the tree with your patch,
rebooted, it worked).
Then, git says:
f078727b250c2653fc9a564f15547c17ebac3f99 is first bad commit

[SCSI] remove scsi_req_map_sg
No one uses scsi_execute_async with data transfer now. We can remove
scsi_req_map_sg.
Only scsi_eh_lock_door uses scsi_execute_async. scsi_eh_lock_door
doesn't handle sense and the callback. So we can remove
scsi_io_context too.

At this moment, the reason for the crash is different then in v2.6.30
I noted the following (I hope to have written the most important stuff).
