Default Bug#649540: ACPI failures on Dell Latitude E6220

Hi,

[CC-ing the relevant Debian bug report.]

Running on a Dell Latitude E6220 with BIOS A03, battery life is
surprisingly low, the thermal zone is always at 25 degrees (although
both coretemp and i8k indicate reasonable values), and reboot hangs
without reboot=pci.

With no parameters, the kernel complains:

> [ 227.525937] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20110623/evregion-478)
> [ 227.525946] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.ECDV.ECR1] (Node ffff880128e7a3d0), AE_TIME (20110623/psparse-536)

A full log is attached; the output of acpidump is on

http://www.pps.jussieu.fr/~jch/private/latitude-e6220-acpidump.txt

(I cannot attach it since it apparently trips a virus scanner somewhere.)

Adding acpi_serialize causes udev to hang; if you wait for long enough,
udev enters a timeout loop (repeatedly timing out when trying to call
modprobe).

Adding reboot=pci makes reboot work.

Adding ec_delay=1000 has no apparent effect.

Adding pcie_aspm=force has no apparent effect.

Default Bug#649540: ACPI failures on Dell Latitude E6220

fixed 649540 3.1.5-1
thanks

This issue appears to be worked around by

linux-image-3.1.0-1-amd64 3.1.5-1

Note that it is *not* fixed by

linux-image-3.2.0-rc4-amd64 3.2~rc4-1~experimental.1

The result is that idle time on battery *doubled*. I'm now getting
4 hours idle time on the small (3 cell) battery, which is what I was
expecting when I bought this laptop.

In case you're interested in what's going on under the hood -- the
kernel is now able to put the processor in one of the low-power
"package" states. Previously, the cores were able to switch to
low-power states, but the package remained in PC0.

Juliusz,

I agree that kernel 3.1.5 (and 3.1.6) does not exhibit the "method
parse/execution failed" ACPI error, whereas 3.2~rc4 does.

But what seems to really make a difference is adding i915.i915_enable_rc6=1 to
GRUB_CMDLINE_LINUX in /etc/default/grub (and run update-grub), not using a
different kernel. Despite the ACPI error, using this option with kernel 3.2
boosts battery life and turbostat shows the package reaching PC7 more than 90%
of the time.

In other words, I am not convinced this ACPI issue is related with the battery
life (but I must admit I do not understand a lot about power-saving stuff).

Best regards,
