Kernel 2.5.55 failed to boot with ACPI support

From: Ole J. Hagen [mailto:[email protected]] I just wanted to inform that kernel-2.5.55 failes to boot when ACPI support is
compiled in the kernel.I have following configuration; Dell Optiplex GX-240, Pentium 4 (1.5 GHz), ATI RAGE 128.
How exactly does it fail?
My brand new Dell Latitude C640 oopses on boot in 2.5.56 if I
have CPU_FREQ config'd in. ACPI without CPU_FREQ is okay - well, it screws my framebuffer screen (what 2.4.21-pre3 doesn't) when the ACPI code does its bootup printk's, but after that the screen recovers.
Another thing is that /proc/acpi/fan is empty despite my setting
of CONFIG_ACPI_FAN=y.
Oh, and one more - /proc/acpi/battery/BAT0/state claims
charging state: unknown
as well as
present rate: 0 mA remaining capacity: 0 mAh present voltage: 0 mV
and the info file, when cat'd, prints a few times
dsobject-0188: *** Warning: Buffer created with zero length in AML
Back on topic, if you're interested I can rebuild my 2.5.56 with
CPU_FREQ and write down the backtrace of the oops.

Would be great if you could do that - and tell what oops it is (NULL pointer dereference etc.), in case you still see that on your screen.
