[NOTES:
 * This report has been delayed, because I had to go through all of the
   entries and filter out the fixed ones, invalid ones etc.  Of course, I might
   have missed some, but hopefully not too many.
 * E-mail reports from the last 7 days are not included.]

This message contains a list of some post-2.6.33 regressions introduced before
2.6.34, for which there are no fixes in the mainline known to the tracking team.
If any of them have been fixed already, please let us know.

If you know of any other unresolved post-2.6.33 regressions, please let us know
either and we'll add them to the list.  Also, please let us know if any
of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

Still existing in 2.6.34 and 2.6.35 HEAD, however a patch fixing the issue 
for b2c2-flexcop/ flexcop-pci has been posted last week:

So, now we have two patches for slightly different issues?

* http://lkml.indiana.edu/hypermail/linux/kernel/1006.0/00137.html
  ...fixes the flexcop-pci.c driver.

* http://patchwork.ozlabs.org/patch/52978/
  ...fixes "some bogus firmwares include properties with "/" in their
  name". I'm not sure if this would make the flexcop-pci.c badness go 
  away too. 

Anyway, both patches are not upstream yet, but Michael mentioned that 
Grant Likely or Ben might push it eventually.

Thanks,
Christian.

On brief review, they look like completely different issues.  I doubt
the second patch will fix the flexcop-pci issue.  I'll pick up the
device tree patch, but the flexcop-pci patch should go in by the
v4l/dvb tree.

Yes, the latter patch dodges the issue with flexcop driver by simply
skipping the directory creation, but both patches should be applied IMO.
The former to fix the flexcop driver because we can trivially fix it,
the latter to solve problems with any generic bogus firmware.

I think we've crossed wires.  By second patch I mean the patch that
changes OF code.  That change has absolutely no bearing on the
flexcop-pci driver.  The patch to the flexcop-pci driver looks correct
to me, but it is completely unrelated to the OF badness.

[Eric Miao]

Rafael and Pavel,

I can boot successfully on my akita/corgi with my 2.6.35-rc3 kernel.
I'll find some time to test v2.6.34 though.

Pavel,

Is any more update on your side?

This one is long solved. 2.6.34 works for me, as does 2.6.35-rc2.

  The fix went in shortly before 2.6.34 was released (commit

Borislav,

I believe both of the issues I encountered that are part of this bug
entry (missing/superfluous slab inclusion issues and cfq related boot
crash due to popcnt/hweight stuff) have a known fix [1] but I am not
sure if any of it actually landed in -git. Quick search through
git.kernel.org log doesn't show anything relevant.

I think there was ongoing discussion on the hweight include fix - so
keeping this open until fixes are in may be what we should do as of
now.

Thanks.

I don't know whether the SLAB issue is related but
the hweight fix is in -tip and hasn't gone mainline yet:

I applied the fix by hand and still no dice. So although
cfq_close_cooperator still shows up in the oops - this seems to be
unrelated to the hweight fix?

I should update the bug report - SLAB is separate issue, cfq one is
another and happens with SLUB.

Thanks
