Ah, then. As far as I can see it was 2.6.27-7.16 (the kernel from release I
think). So more or less quite old as well. The problem with telling the
installer to keep the old version keeps you from using updated kernels as well.
I actually thought that (maybe the entry would have to be outside th
Ah, I hadn't specified the 2.6.28-11 kernel, it was still booting the
old one. (2.6.27-something). Booting 2.6.28-11 now.

There should be no need to do more. What is 'cat /proc/version' when you

Unfortunately all debugging in either acpi or the cpufreq module has to
be enabled at compile time and it is not for the "normal" kernels.

Sorry to say so, but this was not with "cpufreq.debug=7" as a kernel parameter.
See "Kernel command line: root=UUID=dbb5c117-c690-4c20-a4bc-bfb6e5c87877 ro
quiet splash" in the log.

It might be related to the fact that acpi-cpufreq is built in now and
