Hi,
I have an issue starting with 3.2 kernel on my Thinkpad x201s. I've
reported a bug on kernel bugzilla
(https://bugzilla.kernel.org/show_bug.cgi?id=42615) but I'm not too sure
anyone reads it so I'm re-reporting it here. It looks like the same bug
as https://bugs.launchpad.net/linux/+bug/917962.
Basically everything is explained in both bugs, but here's a summary.
When I first upgraded to the 3.2 linux-image package (the system runs
Debian sid amd64), few seconds after the boot is complete I got the
following BUG():

I successfully reproduced using vanilla kernel, so I started bisecting.
I did two bisect rounds (complete log on the bug reports) and found the
first bad commit to be:
a2c76b83fdd763c826f38a55127ccf25708099ce is the first bad commit
commit a2c76b83fdd763c826f38a55127ccf25708099ce

This patch fix it up.

Reverting this commit on top of 3.2.1 removes the BUG().
If you need anything more, please ask.

Very odd, it wouldn't seem that this patch would cause such a problem,
as it is "obviously" correct.
Kuninori, any thoughts about this? Should I revert this from the tree?
thanks,

Something puzzles me. Just after posting I noticed that 3.2.2 was
released, so i tried it (vanilla), and I didn't get the BUG().
Will git bisect work in a forward way (3.2.1 is bad, 3.2.2 is good).

The funny thing is that I don't think there's any x86 system out there
with this *DRD* controller :-) Specially when you consider the fact that
it's very recently that we dropped the ARCH dependency with commit

I don't think so, I think this was a bad bisection.

Out of curiosity, what is a DRD controler?

Maybe (especially since the first bad commit is a merge commit, so I'm
not completely sure I did correctly the second bisect). But I'm puzzled
why reverting the commit on top of 3.2.1 fixes that. And now that Felipe
mentions it, USB Gadget is not even compiled, so I'm completely lost.

Dual-Role Device. This Renesas controller can act as Host or as
Peripheral controller.

Hehehe :-) That's fun... Maybe it's some other instability and it just
didn't kick when you reverted that commit. It could be that the problem
is somewhere completely different and you just didn't fully debug it yet
:-)

I was very much surprised at this issue.
As Felipe explained, renesas_usbhs was for SuperH system.
x86 can not use it,
but, if your PC has "renesas_usbhs.ko" as kernel module,
and loaded it somehow...

Then I guess I did something wrong at bisect time (wether the first or
the second). I'll try to redo it and report back.
Sorry for wasting your time.

I redid the bisect a bit more thoroughly, using the (original) exact
same config as the Debian kernel. I get:
git bisect bad
ec7ae517537ae5c7b0b2cd7f562dfa3e7a05b954 is the first bad commit
