Actually yes, here it looks (when I load msr) like:
# ls -l /dev/cpu/0
insgesamt 0
crw------- 1 root root 202, 0 Jan 26 23:33 msr
When I check /proc/cpuinfo I see that "msr" is listed in the "flags"
section. So why doesn't the driver load automagically?
But then, at least with the version of the checker-script here, it
doesn't seem to make any difference, at least for whatever the script
tries.
Don't know if enabling msr will do me any good otherwise.
