In case you are already aware of the issue, feel free to ignore this mail. I just want to make aware that there could be multiple interrelated (bug) reports that might be considered in conjunction and not on their own, given that the amount of affected users is above average (I could imagine this is not limited to ask.Fedora).
As far as it concerns ask.Fedora: since 6.3 was introduced, we have many users in ask.Fedora with issues that seem to be ACPI related (more precisely, `ucsi_acpi`, but maybe not just this) and that makes it impossible to use kernels after 6.2.15 except with `module_blacklist=ucsi_acpi`.
I already asked the users to provide a bug report (this is how I became aware that the report template was broken ;), but I am not sure if the report(s) illustrate the number of users that have come up with the same issue. Since not all users with issues end up on ask.Fedora, we don't know the actual number of affected systems, but so many users with the same kernel issue is a seldom phenomenon.
So far, most users with 6.3.X ACPI-related issues are found in this topics:
https://discussion.fedoraproject.org/t/fedora-hangs-on-boot-after-upgrading-...
-> black screen after grub menu with stable kernels after 6.2.15 -> everything fine with 6.2.15 -> mitigation: module_blacklist=ucsi_acpi (several users confirmed this to mitigate the issue)
Links to the related bug reports are contained.
The nvidia-driver issue that has accidentally merged in this topic is something different (the nvidia case is alredy solved anyway by an earlier kernel fix). The case in which already 6.2.15 was affected seems to be something different as well.
Except those nvidia-driver-users where a fixed kernel already solved the issue, in the cases where we identified it, affected users had `cat /proc/sys/kernel/tainted` = 0. Of course not all useres provided documentation so we cannot know for sure if that applies to all.
Additionally, it might be noted that we have further reports on ask.Fedora where users have issues that could have a link to ACPI, but not to `ucsi_acpi` in specific - so far it is only the correlation that 6.2.15 works but everything later not, and that the respectively described issue could be explained by ACPI-related bugs (don't know yet). One F37 user consolidated their data in this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=2213179 -> here the mitigation is removing the KVM switch in between system and monitor, although it works fine in 6.2.15. I think that's all reports with noteworthy data/documentation.
Not sure if we have further related reports elsewhere. Also, I check at the moment only those topics that are explicitly added to the #kernel category since I have little time, so maybe we have more reports about it.
Best, Chris
