git bisect log
Hello!
My system Debian Booksworm failed to boot with recently introduced kernels 5.16
and 5.17. git bisect shows problematic commit is:
d6b88ce2eb9d2698eb24451eb92c0a1649b17bb1 "ACPI: processor idle: Allow playing
dead in C3 state"
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6b88ce2eb9d2698eb24451eb92c0a1649b17bb1
This commit also mentioned as problematic with 'IBM Thinkpad T40' systems,
seems like it affecting my machine as well:
https://patchwork.kernel.org/project/linux-pm/patch/[email protected]/
Recompiling kernel-5.17.3-1 (including debian patches and reverting d6b88ce
makes kernel boots!) Without reverting the commit, it freeze at the point where
"ata1" initialized. System freeze before kernel finished loading. Notebook fan
spins at 100% speed and probably 100% cpu load (look like dead loop lock).

Full bisect log attached.
