dmesg 2.6.32
Most recent kernel where this bug did not occur: 2.6.31.6 stock from Arch Linux
Distribution: Arch Linux
Hardware Environment: Asus Notebook X5DIJ-SX101L
Software Environment: n/a
Problem Description:
Since installing the new kernel there a many ACPI Errors in dmesg:
ACPI Exception: AE_AML_BUFFER_LIMIT, Index (000000064) is beyond end of object
(20090903/exoparg2-445)
ACPI Error (psparse-0537): Method parse/execution failed
[\_SB_.PCI0.SBRG.EC0_.STBR] (Node ffff88007d81d120), AE_AML_BUFFER_LIMIT
ACPI Error (psparse-0537): Method parse/execution failed
[\_SB_.PCI0.VGA_.LCDD._BCM] (Node ffff88007d8373a0), AE_AML_BUFFER_LIMIT
ACPI Error: Evaluating _BCM failed (20090903/video-528)
I didn't notice any problems yet, maybe graphics in X are a bit slower but the
biggest problem for me is the spam in dmesg. I found a bugreport (#9558) with
ACPI errors that looks similar to mine except the part in square brackets. I
have read about using a custom DSDT but the final solution in the other
bugreport was a patch for Sizeof operator.
Thanks for your support.
Steps to reproduce: Install Arch Linux and kernel 2.6.32, type dmesg in a
terminal.
