Strange ACPI errors sometimes after resume from s2disk

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
[42017.025050] ACPI: EC: acpi_ec_wait timeout, status = 0x1a, event = "b1=0"
[42017.025197] ACPI: EC: input buffer is not empty, aborting transaction
[42017.025254] ACPI Exception (evregion-0419): AE_TIME, Returned by Handler for [EmbeddedControl] [20080609]
[42017.025350] ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.PCI0.SBRG.EC__.BAT1.UPBS] (Node f78353b0), AE_TIME
[42017.025546] ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.PCI0.SBRG.EC__.BAT1._BST] (Node f7835400), AE_TIME
[42017.025715] ACPI Exception (battery-0360): AE_TIME, Evaluating _BST [20080609]

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:

Please try changing msleep(1) to udelay(50) in drivers/acpi/ec.c

have msi-laptop module loaded?

Please fill a bugreport and attach all the information there.
