Last I heard the reporter was going to attempt a bisect, that was a 
while ago. I don't really have any suggestions other than that.

I've been having trouble reliably bisecting; sometimes seemingly-bad
kernels work OK and other times thought-OK kernels fail even though I've
stopped Gnome and HAL.

At this point I'm suspecting intermittent hardware failure and am
getting set up to test on a similar machine.

I'm trying to get an ftrace profile that covers the point in question,
but it might take me a couple of days.

No, it's now hanging 20 seconds much later, after returning to
userspace :( But the dmesg log still has a hang of ~20.5 seconds just
like before, between two kernel messages...

Hmm.  Can you try to comment out suspend_device_irqs() and resume_device_irqs()
in drivers/base/power/main.c and see what happens?

Oddly, that does seem to help. I'm sure it can't be a solution though :)

Not really. ;-)

Still, something like the (untested) patch below can be.  Can you please give
it a try?

Seems to work, though I'm not sure yet whether it really helps, that
needs some more verification, will let you know tomorrow.

Hmm.  The patch shouldn't matter for this box, except for one thing:
check_irq_resend() on resume.  Interesting.

The problem doesn't always happen. But now that it happens here again,
maybe I can try ftrace again...

Alright, I have managed to trace this.

http://johannes.sipsolutions.net/files/hibernate-delay-dmesg.txt

has the dmesg, you can clearly see the delay:
[50265.143330] ACPI: Waking up from system sleep state S4

I managed to get an entire function trace between

[50265.143330] ACPI: Waking up from system sleep state S4

and

[50290.439040] Restarting tasks ... done.

which I've uploaded to

http://johannes.sipsolutions.net/files/hibernate-delay-trace.bz2

(WARNING: uncompresses to 574MiB!)

I'm not sure why the timing in there doesn't show the delay, Steven was
taking a look at that.

Quite frankly, it looks like resume_device_irqs() itself causes the delay to happen.

The next step would be to put a couple of printk()s in there and see which part
of it triggers the delay.

Rafael

The other one is a _powerbook_ bug, very different machine (powerpc
mac). macbooks are just almost ordinary x86 gear :-)

I'll try to tackle the trackpad problem.

Yes, I realized they were different.

Perhaps the VIA-PMU interrupt shouldn't be disabled in
suspend_device_irqs()?

Possibly, but then we did use to have all interrupts disabled
at some stage before going to suspend_late anyway no ? So it shouldn't
make a big difference.

The VIA interrupt must not be HW masked in the PIC on some machines
because it's the wakeup source, so we may have to force re-enable it
since it can be lazy-disabled, but those aren't the machines with the
trackpad problem so I think I'll need to have a closer look at what's
going on and get my head around it.

Haven't had a chance yet, hopefully today or tomorrow.

Ben.

FWIW, I'm no longer able to make this happen.  No idea what has
changed...  But it seems to be gone, and nobody else has complained, so
I guess it's a non-issue for 2.6.30.  It can probably be removed from
the list.

Thanks,

But it should definitely be retitled -- the commit bisect pointed out
has little to do with the problem. And Handled-by should point to Ivo
since he was asking for debugging info and stuff.

Retitle to "rt2x00: slow wifi with correct basic rate bitmap" or
something like that, it's not a bug in mac80211.

Hello,

I am sorry for responding to your e-mail late. Takashi Iwai identified
the cause of this problem and provided a patch. I tested the patch and
confirmed that it solves the problem. The patch was integrated into
mainline with the following commit:

=== 8< ===
commit 461c6c3a0a23a8fac1a4b636e93ff5dfe599a241
Author: Takashi Iwai <tiwai@suse.de>
Date:   Mon May 25 08:06:02 2009 +0200

    ALSA: hda - Add missing check of pin vref 50 and others in Realtek codecs
    
    Some Realtek codecs like ALC861 seem to support only VREF50 while the
    current driver assumes it's only VREF80.  Check other VREF bits to set
    the correct value.
    
    Signed-off-by: Takashi Iwai <tiwai@suse.de>

paga_legacy remains broken in 2.6.30-rc8, and I still have to
apply the above-mentioned patch to make the affected machine boot.

2.6.30-rc7: Reported regressions from 2.6.29

[Rafael J. Wysocki]

[NOTE:
 Bug entries for which I know there are working patches get the
 RESOLVED / PATCH_ALREADY_AVAILABLE status in the Bugzilla, which
 makes it easier to check if the patches have been merged before sending
 out the list.  For this reason, please let me know of working patches
 for any of the regression list items or (better) change the status of the bug
 entries in case you know of a working patch (in which case please also add
 a link to the patch to the appropriate bug entry).]

This message contains a list of some regressions from 2.6.29, 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 2.6.29, 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.
