Ah - this was reported as a 2.6.26 -> 2.6.27 regression, not a
.27->.28-rcX regression.

Even so, it's not obviously an XFS regression as the problem is
that alloc_pages(GFP_KERNEL) is the new failure on .27. The fact
that XFS never handled the allocation failure is not a new bug
or regression - it has never caught failures during log
allocation...

So really, if you want to look for a regression here, it is the
change of behaviour in the VM leading to a memory allocation failure
where it has never, ever previously failed...

Cheers,

Dave.

OK, I moved it to the list of regressions introduced between .26 and .27.

Pulled from Linus's git today so it is a 2.6.28-rc2+ kernel and this is
still a regression I was able to hit.

[Bug #11841] plenty of line "ACPI: EC: non-query interrupt received, switching to interrupt mode" in dmesg

This message has been generated automatically as a part of a report

The following bug entry is on the current list of known regressions

It's expected that you see that message on both boot and every wakeup from suspend.

If you look at the dmesg Francios' posted, his issue is that there are _floods_ of this message during boot.  That's not expected :).

I see these messages already with 2.6.27.3:

  # grep non-query /var/log/dmesg
  [    0.205977] ACPI: EC: non-query interrupt received, switching to interrupt mode

There are 9 more occurrences in the current ring buffer:
  # dmesg |grep non-query | wc -l
  9

Each one happens right after waking from S3 sleep, for example:

  [70168.288590] CPU1 is up
  [70168.288594] ACPI: Waking up from system sleep state S3
  [70169.624254] ACPI: EC: non-query interrupt received, switching to interrupt mode

The setup is a TP T60 w/ Intel graphics, wireless (i.e. no taint),
Debian unstable, but with vanilla kernel 2.6.27.3.
