Created attachment 300836 [details] 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/80742062-8629-3978-e78d-92ffc9bb2e0b@gmail.com/ 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). https://linux-hardware.org/?probe=59b41381ed Full bisect log attached.
Probably, already in progress: https://patchwork.kernel.org/project/linux-acpi/patch/20220421133634.19489-1-ville.syrjala@linux.intel.com/
new test: 5.18-rc4 failed.
have you tried if 5.18-rc5 helps, which contains the patch you mentioned in comment 1?
I've been told to try 5.18-rc4 for patch to test. That was a mistake. 5.18-rc5 works! Thanks!
