Comment 1 for bug 66812

Same problem here after upgrade!
but I'm using a P 4 -M

cat /sys/devices/system/cpu/cpu0/crash_notes
1fe62800

cat /proc/cpuinfo | grep name
model name : Mobile Intel(R) Pentium(R) 4 - M CPU 1.70GHz

As a workaround I got it working when I added "p4-clockmod" to /etc/modules

With this module loaded everything seems to be ok now in /sys/devices/system/cpu/cpu0/
on my system after reboot!
