Problem Description:acpi_cpufreq driver will not load, says no device.
i am having the same problem as someone posted on bug 9486 with an hp laptop
and not being able to load this driver
as listed in bug 9486 post #13, i have compiled a debugging enabled kernel and
booted with the requested options. I have the dmesg and acpidump from booting
into a 2.6.24.3 kernel built with debugging for acpi
The original poster does not seem to have followed up by posting a new bug, so
since I am having this problem, I want to pick up where he left off.
when i run acpidump -o acpidump.txt i get the message afterwards that bad
checksum for generic tables.
of note from dmesg that i can tell is :
ACPI Error (exnames-0219): Bad character 01 in name, at ffffc20000609067
[20070126]
and
Marking TSC unstable due to TSCs unsynchronized
if there is anything else i need to add please let me know.
Steps to reproduce: boot any prebuilt kernel from a distribution or a self
build kernel downloaded from kernel archives.
