We regularly see bug reports over this one, however it is a write to
a read-only register which some operating systems (including Linux)
tend to write to once in a while.

Ignore the writes since they do no harm.


Does Linux write it with wrmsr_safe()? If not, I don't see how it works. If it does, then we shouldn't ignore the write, instead issue the #GP as usual, but be silent about it.
