Kernel Bug Tracker – Bug 8909
hangs on boot
Last modified: 2008-10-17 21:31:48 UTC
Hangs on boot with:
ACPI: EC: GPE = 0x4, I/O: command/status = 0x66, data = 0x62
ACPI: Interpreter enabled
ACPI: (supports S0 S3)
ACPI: Using PIC for interrupt routing
ACIP: EC: GPE = 0x4, I/O: command/status = 0x66, data = 0x62
2.6.23-rc2 is ok
2.6.23-rc3-latest (7c010de7506954e973abfab5c5999c5a97f7a73e) bad
git-bisect narrowed it down to:
ACPI: EC: Switch from boot_ec as soon as we find its desc in DSDT.

Some ASUS laptops fail to use boot time EC
and need to eventually switch to one described in DSDT.

*** Bug 8919 has been marked as a duplicate of this bug. ***
please confirm that this issue is not present in linux-2.6.23-rc3-git9
or later -- as the original patch to bug 8709 has been reverted from that release.
-git9 (50c46637aa894f904e2fb39086a3d7732f68bd50) still boots
Thanks for verifying that this regression is gone before 2.6.23-rc4.
This bug is closed, but perhaps you can test the latest patch
in bug #8709 to help us make sure it doesn't come back?
