hello,
netbsd crashs at Dell M710. You can have a look at the screeshot at

Any Ideas what could be the problem?
Most probably, an attempt to read a MSR, which is not allowed/present
for that CPU.
At ddb prompt, type "bt" and "show reg", so we can see where and how it
happens.

MSR 0xcd, which is MSR_FSB_FREQ.
One hacky fix is needed. You seem to be in the same situation as mine
there, quick glance at your CPU ID makes me think it reports model 0xc too:

I asked for a pull-up about a week ago, so should come in eventually.
Try patching around as I did.
the patch solves the problem. unfortunately the kernel now has a problem
with the broadcom nic.

does there also a patch exist for this problem?
Thank you for your efforts
