bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1107644
We are working on Debian 10 OS version and Intel Xeon-2775TE HW model
platform. We found a grub issue about the grub menu being 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 my colleague already raised a bug with url:
https://savannah.gnu.org/bugs/index.php?66257 and attached related fix
patch both to bug ticket and this mail's attachment. In patch, he did a
detailed explanation and some information from Intel's expert. This patch
was accepted by the grub community on Dec 9 2024. We are eager to merge
this fix with Debian12, so that Debian12 users will not meet this issue any
more.
