The patch should definitely be merged as it fixes a problem. Andrew,
will you send it to Linus ? There's no fbdev maintainer anymore...

Here's the up to date patch (same as previously posted minus a warning
that was due to a now unused variable that I removed in this one). It
doesn't fix -other- problems reported with suspend & shutdown that have
been elusive so far (I really haven't reproduced despite some serious
torturing) and could be X bugs in the first place. I'll continue
investigating them but in the meantime, this should go in.

radeonfb: Fix problem with color expansion & alignment

The engine on some radeon variants locks up if color expansion is
called for non aligned source data. This patch enables a feature of
the core fbdev to request aligned input pixmaps and uses the HW
clipping engine to clip the output to the requested size

Still with us on -rc6, nasty, reproducible, no clues on what can be.

VC switch locks or delay the systems minutes, resuming from suspend locks hard 
the machine.

2.6.28-rc is unusable here.

Jesse, any hints? My suspicion that it can be the same thing happened with bug 
10620 is wrong? (It was a very similar error about vblank...)

Just added to the bug, it looks like a DUP of an issue Keith just fixed last 
week (now to make sure the patch makes it upstream quickly).

I can confirm that, with the patch from 
http://lists.freedesktop.org/archives/intel-gfx/2008-November/000614.html 
applied on top of current git head (rejected hunk in 
drivers/gpu/drm/i915/915_irq.c due to the additional 
dev_priv->irq_mask_reg = ~0; in git between the removed lines, I kept 
it) I can suspend/resume and do a VC switch again.

Big thanks!

Bernhard

Excellent, thanks for confirming.  I just pinged the maintainer, hopefully we 
can get this patch pushed quickly.

not tearing down the drm vblank structure.

git log drivers/misc/thinkpad_acpi.c shows no changes since August 1st,
so I thing it's save to assume that the regression still exists.

    tracing: fix mmiotrace resizing crash
    
    Pekka reported a crash when resizing the mmiotrace tracer (if only
    mmiotrace is enabled).
    
    This happens because in that case we do not allocate the max buffer,
    but we try to use it.
    
    Make ring_buffer_resize() idempotent against NULL buffers.

I can reproduce this problem on Toshiba Portege R500, with the same symptoms
(please see the bug entry for details).

Well, we have at lease three DRM-related regressions in 2.6.28-rc and no
visible reaction from the developers/maintainers of the code in question. :-(

Thanks,
Rafael

Sorry, I've been away for awhile.  I'll dig through the latest info on these 
regressions today.

Looks to be fixed in -rc6:

-Calibrating delay using timer specific routine.. 6198.05 BogoMIPS (lpj=12396107)
+Calibrating delay using timer specific routine.. 6399.82 BogoMIPS (lpj=12799647)
[...]
-checking TSC synchronization [CPU#0 -> CPU#1]:
-Measured 696 cycles TSC warp between CPUs, turning off TSC clock.
-Marking TSC unstable due to check_tsc_sync_source failed
+checking TSC synchronization [CPU#0 -> CPU#1]: passed.

So, BogoMIPS value on CPU#1 is in line with CPU#0 again and TSC passes.
No idea what commit would be responsible.

Cheers,
FJP

Hi,

2.6.28-rc6 (or more precisely:
ed313489badef16d700f5a3be50e8fd8f8294bc8) still hangs my Mac after
resume, and git log drivers/acpi/sleep/main.c shows no relevant commits.

I'm not getting a freeze here(was getting strange cpu frequencies
though); My setup here is the latest xserver from intrepid
readeon, and s2ram app. echo mem > /sys/power/state gives
me a black screen, then an instant reboot. s2ram recovers
as expected. Although I'm not sure what the setup is with macmini,
I've a macbook pro ati chipset.

either and I'll add them to the list.  Also, please let me know if any of the

It is fixed for me in -rc7-105 (to be exact, it seems that commit 52440211dc 
fixed it), but there are more people with a very similar problem still unfixed.

2.6.28-rc5: Reported regressions from 2.6.27

[Rafael J. Wysocki]

[NOTES:
 (1) Due to some recent controversies, in future I will only use 'Handled-By'
     tags for people who actually submit a patch or provide substantial help to
     the reporter (like advising him which commits to revert etc.).
 (2) We have almost as many regressions with patches as unresolved ones and
     the majority of these patches have not been merged for over two weeks
     (for almost three weeks in many cases and for over a _month_ in one case).
     IMO, this is insane.]

This message contains a list of some regressions from 2.6.27, for which there
are no fixes in the mainline I know of.  If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.27, please let me know
either and I'll add them to the list.  Also, please let me 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.

Continue to malfunction. More details on the bugzilla entry. But basically, I had:

- one complete lock on VC switching (not switching back, just pressing ctrl-alt-f1).
- 3 two-plus minutes delay on VC switching
- a complete freeze on resuming from ram (not even SysRq-b working).

OTOH, it seems that VC malfunctioning happens only with "visual effect" aka 
compiz on.

Back to 2.6.27.5. This is quite worrying now... should I try to start a
bisection? Although I know from experience that bisecting over a -rc1 is quite
painful.
