I am not sure what is going on to cause this transition
frequency failed. It would be a big help if you could rebuild 
the driver for debug and post the system log (dmesg) of this
failure. 

Thanks. Paul.

As I wrote in a private mail to your colleague Mark Langsdorf,
everything is fine if I disable CONFIG_ACPI_PROCESSOR and
CONFIG_ACPI_FAN in my kernel configuration.

Here are two debug dmesg:

Strange, works for me:

modprobe powernow-k7 overwrite_table=1 multiplier=50,60,70,80,90,110

dmesg:

2.4 patch and powernow-k8

I've been trying to patch cpufreq into a recent 2.4 kernel and having 
some problems.  When I've config'ed powernow-k8 to be static linked, I 
get the below errors.  Compiling as a module works, but yields 
unresolvable symbols when trying to load the module.

The speedstep-centrino seems to build fine (though I can't test it on my 
laptop), and I'm guessing there is a build issue in which symbols are 
exported.  However, I don't actually understand the build process enough 
to make any headway...

BTW:  I've tried on kernels 2.4.25 -> 2.4.28, and tried a couple 
different snapshots from ftp://ftp.linux.org.uk/pub/linux/cpufreq/ as 
well as the latest stuff in the cvs repository.

Any help would be appreciated,

I can't quite reproduce this error on my AMD64 system, but 
I can get something awfully close, in that I see the undefined
reference error.  I have no idea what the problem is.  It only
happens when the powernow-k8.c code is compiled, but I can't
see anything in the code that would produce that.

This is occuring on RHEL3 U2 with gcc-3.2.3.  Anyone have
any ideas?

Could you try out removing the "__devexit_p" in 
static struct cpufreq_driver cpufreq_amd64_driver = {
        .verify = powernowk8_verify,
        .target = powernowk8_target,
        .init = powernowk8_cpu_init,
        .exit = __devexit_p(powernowk8_cpu_exit),
