Package: firefox-esr Version: 128.8.0esr-1~deb12u1 Ever since I upgraded to Debian Bookworm and started using the Nouveau video drivers (see details below), I experienced random system hangs. My mouse would stop responding, video would stop updating, keyboard would stop working (at least visibly), I could not exit X with Ctrl-Alt-F1, and my only recourse was to use SysRq to sync/umount/boot.
If I rebooted prophylactically every other day, I could sometimes avoid the lockups, but there were often times I wasn't so lucky. I assumed this was because the Nouveau drivers are experimental and that someday I'd have to start debugging at the kernel level to figure out how to stop it. Then one day recently, the crashes randomly stopped! My system was amazingly stable for days at a time. The other day, the security release for firefox-esr 128.8.0 came out, I upgraded, and the hangs were back. Presumably firefox was doing something to tickle bugs in the nouveau drivers, but whatever it was, it didn't happen in version 128.7.0esr-1~deb12u1. It did in previous firefox versions. I looked at firefox-esr's git repo from https://salsa.debian.org/mozilla-team/firefox.git I noticed that by chance, version 128.7.0 did not include the "fixes" or the "debian-hacks" branches. They appear to not have been merged for some reason. This leads me to believe that there is something special in those commits that is causing my Nouveau issue. I could build some test packages, but before I do that, I was hoping the experts would know which commit or set of commits are the most suspicious, and which I should try removing first.
