Description Andrey Ovcharov 2009-12-03 18:18:19 UTC 
First of all kernels before 2.6.32 did not observe anything like that. 

All necessary information about my hardware is here http://ru.gentoo-wiki.com/wiki/Acer_Aspire_5730ZG

In sys-kernel/vanilla-sources-2.6.32 and sys-kernel/gentoo-sources-2.6.32 after loading the same symptoms: in the first place is not working brightness control for display; second in dmesg watch spam 

"ACPI: EC: input buffer is not empty, aborting transaction"

"ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.AMW0.WMCA] (Node ffff8800bbc3f3e0), AE_TIME
ACPI: EC: input buffer is not empty, aborting transaction
ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20090903/evregion-424)"

the third is markedly reduced performance.

the spam in dmesg is very similar to this error http://bugzilla.kernel.org/show_bug.cgi?id=13689
