dmesg reports to me stuff like
ACPI Exception (evregion-0424): AE_TIME, Returned by Handler for [EmbeddedControl] [20060707] ACPI Exception (dswexec-0458): AE_TIME, While resolving operands for [OpcodeName unavailable] [20060707] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC0.BAT1._BIF] (Node ffff8100020368d0), AE_TIME ACPI Exception (acpi_battery-0148): AE_TIME, Evaluating _BIF [20060707] ACPI: read EC, IB not empty ACPI Exception (evregion-0424): AE_TIME, Returned by Handler for [EmbeddedControl] [20060707] ACPI Exception (dswexec-0458): AE_TIME, While resolving operands for [OpcodeName unavailable] [20060707] ACPI Error (psparse-0537): Method parse/execution failed [\_TZ_.THRM._TMP] (Node ffff810002032d10), AE_TIME
It never used to complain at all. This is an amd64 laptop, and related symptoms include
- kpowersave not being able to monitor the batter or AC adapter correctly; leading to catastrophes like laptop powering itself off with no warning, loss of work, filesystem needing log recovery, and so forth.
- Serious fan action. Recent kernels seemed to finally be doing sane things so that e.g. just editing text kept the CPU cool ... but now it's on almost all the time, CPU is very hot.
What's an AE_TIME?
I'm not quite sure where these problems crept in, but I never saw such stuff with 2.6.18 at all.
