2.6.31-rc5-git5: Reported regressions from 2.6.30

[Rafael J. Wysocki]

This message contains a list of some regressions from 2.6.30, 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 2.6.30, 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.

Ivo sent a test patch for this and I tested it., but without success. I reported my findings but 
didn't get a reply. See http://marc.info/?l=linux-wireless&m=124940189007154&w=4.

I suspect the failure is due to the same PS hardware probelms that were at the route of my original 
report.. Unless one of the wireless folks say otherwise, I think we should close this on the basis 
of busted hardware. I'm happy to simply eject the card and re-insert it now that I have some udev 
scripts to tear down the wireless configuration on the ejection and set it uop again when the card 
is re-inserted.

Thanks

Chris

This one sounds like an IRQ routing error, so probably ACPI, but we've
been totally unsuccessful at getting any further information out of the
submitter.  Use your own time judgement on this, but if he hasn't been
responding to you either for 36 days, I'd suggest closing this as
unresponsive.

As I noted earlier this comes from the fact that a driver or mac80211
is queuing work onto the mac80211 workqueue when we already ran the
mac80211 suspend callbacks and we haven't yet resumed. There have been
several fixes for these, for both drivers and mac80211. We've already
pushed them to wireless-testing but I do not recall which ones have
been propagated to 2.6.31 as fixes.

So we have two options, we either treat all these as real issues for
2.6.31 and try to backport all related fixes, or we downgrade this
warning to just bail out. The problem with debugging these issues
as-is on 2.6.31 is that the caller which queued the work remains
invisible to the trace from the warning -- the warning comes from the
workqueue callback not the routine which ran queue_work(). This was
recently changed in wireless-testing and we now issue the warnings
from the callers of queue_work() for the mac80211 workqueue so we
*can* easily see the root cause to the issue and easily fix this.

We can surely fix this issue alone but we're sure bound to see this
warning later from other buggy drivers/mac80211 on 2.6.31 so we do
need to address how we want to address this issue as a whole for
2.6.31.

Fabio to help iron out this issue can you please use wireless-testing,
use IBSS as you were and go through the suspend-resume cycle to see if
you see a new warning with ath5k.
