It actually might be unrelated to secure boot. With secure boot the system freeze at boot with a single message on the screen: EFI stub: UEFI Secure Boot is enabled. When I disable secure boot the screen is blank, nothing, kernel doesn't boot. On good kernel (6.6.22) with secure boot I see the message for a second and than normal kernel boot messages; without secure boot I see blank screen and than kernel messages. So, it looks like the kernel just unbootable on my system. I will try to bisect vanilla sources to find a broken commit. Bisected to the following commit: commit 5a70baec2294e8a7d0fcc4558741c23e752dad5c Author: Tejun Heo <tj@kernel.org> Date: Mon Jan 29 08:11:25 2024 -1000 workqueue: Implement system-wide nr_active enforcement for unbound workqueues [ Upstream commit 5797b1c18919cd9c289ded7954383e499f729ce0 ] Looks like kernel command line change fixes the boot failure: -nohz_full=0-7,16-23 +nohz_full=1-7,16-23 (In reply to Ivan Volosyuk from comment #2) > Bisected to the following commit: > commit 5a70baec2294e8a7d0fcc4558741c23e752dad5c > > Author: Tejun Heo <tj@kernel.org> > > Date: Mon Jan 29 08:11:25 2024 -1000 > > > > workqueue: Implement system-wide nr_active enforcement for unbound > workqueues > > > > [ Upstream commit 5797b1c18919cd9c289ded7954383e499f729ce0 ] > > > Looks like kernel command line change fixes the boot failure: > -nohz_full=0-7,16-23 > +nohz_full=1-7,16-23 Nice job, can you report this upstream? https://bugzilla.kernel.org and then post the url here? I contacted developer and he said the changes was never meant for 6.6.x I can see them reverted in 6.6.25 kernel. Great news, thanks for reporting back. |
