Hi Gabe,
If you encounter a further problem which hangs simulation when using O3, please
also cherry-pick this related patch:
https://gem5-review.googlesource.com/c/public/gem5/+/26203, which fixes a
permanent pipeline stalling problem also caused by renaming mode switching.

Thanks Gabe,
Please let me know if you can reproduce the problem with the mentioned patch.
If that’s the case, we should open a JIRA ticket so that I can have a look at
that

Hi Giacomo, thanks for your reply. To answer your questions, it looks like
no for 1 (unless my grep was bad), and checkpoint save/restore for 2. I
think we've been able to reproduce this problem much more easily with older
versions of gem5, likely missing that fix, although I think we may have
also
Hi Gabe,
We are encountering the same problem on top of develop but it’s still worth
asking:
1. Do you have https://gem5-review.googlesource.com/c/public/gem5/+/25743 ?
2. Are you encountering this in a simulation which is using a CPU switch or
checkpoint save/restore
Kind Regards
Giac
