I know I asked this before but I figure the long post may have put  
some people off.


I'd like to eliminate this as a cause of my problem

It appears I can read the value.

#kldload cpuctl
#cpucontrol -m 0xc001001f /dev/cpuctl0
MSR 0xc001001f: 0x00400000 0x00100008

#cpucontrol -m 0xc001001f=0x0040000000100008 /dev/cpuctl0

Causes an nfe0 watchdog timeout and a powerdown failed, so that's  
clearly a dumb thing to do.

Would I be better off asking somewhere else?
