Hi Glenn,

Thanks very much for your tips. We already re-sent the patch by `git send-mail` with theme "[PATCH] BugFix: grub menu gets stuck due to unreliable rdtsc instruction" and cc @Daniel to get his attention to this patch.
Waiting for your feedback.

Hi 段亚勇,

I think you will get more of a response if you use git-send to send
this patch inline (not attached), and to CC Daniel (Daniel Kiper
<dkiper@net-space.pl>). And do periodically check back in. I have the
feeling that Daniel is overwhelmed with some large patch sets and may
take some time to get to this.
