Xen 4.2.0 - CPU Frequency Scaling
...ependently which used to be possible
with the old xen kernel. If further information would be useful please
let me know.
Thanks,
James

Kernel-utils stupidities (readahead and cpuspeed)
...unlevels.
Worse, cpuspeed.
This is from an Athlon64 system, so it is possible that this behavior is
different on non powernow-k8 systems.
On the CentOS4-x86_64 kernels, the cpuspeed-drivers are built into the
kernel. Here, cpu speed-management works, as the
/sys/devices/system/cpu/cpu0/cpufreq/scaling_driver -file exists (tested for
in /etc/init.d/cpuspeed). On CentOS4-i386, the powernow-k8-module is not
built into the kernel, so the above test fails, and the cpuspeed startscript
exits.
There seems to be a plan for this. The /etc/cpuspeed.conf file can specify a
DRIVER variable, but no attempt is...

More Coverity-reported issues.
Another bundle of issues from Coverity triage.
The first one is in x86/mm, and looks scarier than it is. The others
are all in xen/drivers and AFAICT are pretty minor.
Cheers,
Tim.

Xen 4.3.1 / Linux 3.12 panic
Hej folks,
I''ve been trying to get a new machine up and running with the latest Xen for a while on a Slackware64 (current) machine.
After installing Xen from source and building a new kernel with all xen options enabled I haven''t been able to get the machine to behave.
The machine is a brand new dual opteron 6212 on a Supermicro H8DGi board with 64G ECC memory.
