We found a grub issue that grub menu will be stuck with a 1/200 ratio in AC power on/off stress test. After multiple validation and we co-worked with Intel, we found the root cause is unreliable "rdtsc" instruction usage. * *And I already raised a bug with url: **https://savannah.gnu.org/bugs/index.php?66257 <https://savannah.gnu.org/bugs/index.php?66257>** and attached related fix patch both to bug ticket and this mail's attachment. In patch, I did a detailed explanation and some information from Intel's expert. We are eager to merge this fix with grub so that all GNU grub users will meet this issue any more.* *If there is any problem, please let us know by mail or bug ticket.* *We are all looking forward to your feedback!* ------------------------------------------------------------------- Best Regards, Will Duan Shanghai Yangpu District DouYin New Jiangwan Square T2B 3F -------------------------------------------------------------------
