"modprobe msr" fail!

[Mitch Bradley]

CONFIG_X86_MSR=y

means that MSR support is compiled into the kernel, not as a module. So
you do not need to do modprobe. The functionality is built-in. There
will be a file named "/dev/cpu/0/msr".


In image 386, the config was:

CONFIG_X86_MSR=m

so with that build, you did need to do the "modprobe". Before you do the
modprobe, the "/dev/cpu/0/msr" file will not exist, but it will appear
after the modprobe.
