Strange ACPI errors sometimes after resume from s2disk

[Dmitry Nezhevenko]

Hiall. Just got these strange messages with 2.6.27.2. They flood dmesg.. (same block every second). 

[42016.520062] ACPI: EC: acpi_ec_wait timeout, status = 0x1a, event = "b1=0"
[42016.520079] ACPI: EC: input buffer is not empty, aborting transaction

Battery state "freezes" after this.. So if it was charged to 90%, it will
be 90% forever.  Also information about charger (plugged/unplugged) is not
updating... BIOS automatically increases display brightness just after
plugging charger but powersave thinks that it's unplugged.

After turning laptop off I can't turn it on any more.. I can hear fan noise,
but it don't boots (There are no even BIOS splash/message)

I should remove battery and wait ~5 seconds...

v2.6.26 was non-working here, but as far as I remember, there was no such
problem with 2.6.25.  It's very difficult to reproduce it (this is just
second case for ~2-3 weeks).  So bisecting is impossible.

Any ideas? Should I fill a bugreport?

dmesg when this happens is available:
