Bug#493479: linux-image-2.6.26-1-amd64: [SOLVED] Problem was HPET

[Dave Witbrodt <dawitbro@sbcglobal.net>]

Package: linux-image-2.6.26-1-amd64
Version: 2.6.26-1
Followup-For: Bug #493479


After removing all of the boot parameters for debugging as mentioned in my
last message, I then began removing the parameters which disable kernel
features one at time.  The result was that I could remove all of the
options except "hpet=disable".

There are 5 kernel config options for HPET, and they are identical between
my last working custom config for 2.6.25 and the Debian stock 2.6.26-1
kernel:

    CONFIG_HPET_TIMER=y
    CONFIG_HPET_EMULATE_RTC=y

    CONFIG_HPET=y
    # CONFIG_HPET_RTC_IRQ is not set
    CONFIG_HPET_MMAP=y

That is a regression for this machine, with the ECS AMD690GM-M2
motherboard.  (As mentioned in my original bug report, I have another
machine with a Gigabyte GA-M59SLI-S5 motherboard that is not affected by
this regression.)

Are there any Debian-specific changes to the HPET source code, or is the
problem directly from upstream?
