Subject: Strange ACPI errors sometimes after resume from s2disk
Date: Wed, 22 Oct 2008 01:00:34 +0300 [thread overview]
Message-ID: <20081021220034.GA18248@laptop.local> (raw)
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:
