This looks like it might be related to the queue guard in
__elv_next_request() again, could you try this patch:

Thanks for your answer :)
Just tried (patch applied, compiled with make mrproper beforehand), but the
result is pretty much the same.
Interesting enough, If I reboot after using 2.6.38.5 for a while, the first
boot on .6 is successful; following boots fails as shown so I guess that some
hardware status can have a role into this, even if I don't know what happens.
Here you can find the last capture with netconsole, with patch applied. (btw,
how I can 100% sure to have applied it properly, besides checking the kernel
date?)

Well, the first patch was just a guess. It looks like another queue
guard problem. However, I think this one is that the code thinks a dead
queue isn't stopped. Could you try this patch instead?
Thanks,

Ok, just tried (I've had to apply the patch manually, as my
include/linux/blkdev.h is slightly different and patch complained a bit, see
below).
Now it works, the kernel is able to boot correctly and I'm writing from
2.6.38.6.
Many thanks for your time!
PS: actual blkdev.h on my machine:
static inline void queue_flag_clear(unsigned int flag, struct request_queue *q)
{
WARN_ON_ONCE(!queue_is_locked(q));
__clear_bit(flag, &q->queue_flags);
(473)}

Bugzilla report is here:
https://bugzilla.kernel.org/show_bug.cgi?id=35682
The problem occurs if blk_run_queue() or its variants is called after
blk_cleanup_queue() is called. The run checks should have a state guard
for QUEUE_FLAG_DEAD. Since a DEAD queue is always STOPPED, just fold it
into the blk_queue_stopped() test.

Jens, can you look at this, please ... would you prefer a separate DEAD
test instead? Incidentally, this is in addition to the other DEAD test
you still haven't applied ...

Seems a bit of a mixup. Would be cleaner to set STOPPED when it is
marked dead, but I suspect that will kill erroring out IO when the
device goes away unless we add some logic to ensure that happens without
the drivers help.

I had some crashes over here, especially with 2.6.39, but also with some
2.6.38.*, kernel versions, too. Applied this patch about 24h ago and so far
there seem to be no further kernel panics. Since I know no way to actually get
the logs from the crashes, I just photographed them using my mobile phone:
http://imagebin.org/index.php?mode=image&id=155275
http://imagebin.org/index.php?mode=image&id=155274
As you can probably see they are not complete, some output is missing. My
general hardware/setup:
* AMD 64 vanilla kernel (2.6.39)
* Phenom II X6 1055T
* 8GB Ram
* Gigabyte GA-870A-UD3 (rev. 2.1)

That looks like this:
http://marc.info/?l=linux-scsi&m=130635674521428
It depends on a couple of other block fixes, though. Everything will
probably be upstream and back to stable in the next few days.
