Re: [Xen-devel] Powernow-k8 support
Hi,
it seems that the change did work partially. But the frequency can not
be changed.
The kernel freezes when udev is loading the alsa modules and/or the
nvidia module. After that the machine may reboot automatically.
Here some infos I found in my /var/log/messages file:
==== Example 1 ====
Jun 12 01:54:02 desktop kernel: NVRM: Trying to sleep during raised irql!!
Jun 12 01:54:02 desktop kernel: NVRM: are we holding a lock?
Jun 12 01:54:02 desktop kernel: NVRM: skipping os_delay

So it seems that the nvidia driver has some problems with this code
modification??
Attached the last dmesg output. You my look at the end of this file
Thanks in advance
