Hi,
On my acer swift 3 (SF314-51), I can't boot on my device since
4.19.198 (no issue with 4.19.197) without adding "acpi=off" in the
parameters. Same thing happens on 5.12.19 (didn't happened in
5.12.16), 5.13.4 and .5 and 5.10.52.
If acpi is not off issue is :
-black screen after grub,
-no errors, no activity (tested by leaving the pc 10 hours), no tty,
no logs whatsoever in journalctl as if the kernel didn't start. Even
adding 'debug' or 'initcall_debug' doesn't show anything.
If I add acpi=off, the screen blinks one time and boots normally but
after kernel 5.10 (5.12 and 5.13) I loose usage of keyboard and touchpad.
Notes:
- I'm using Manjaro KDE
- I have tested with 4.19.198 Vanilla (config file attached) and same
thing happened
- setting nomodeset doesn't change anything
- tried every acpi parameters, only =off worked
- Bios was not updated, but the bug persisted after upgrading it
- Acpi issue is recurrent with this pc it seems below 4.11

Thank you for your help,

Hi again,
I've done a bisect on the 4.19.y branch and I've found that it is the
commit 2bf1f848ca0af4e3d49624df49cbbd5511ec49a3 [ACPICA: Fix memory leak
caused by _CID repair function] that introduced the bug. By doing a git
revert and building the kernel I can boot normally but as long as this
commit exist I just get a black screen as explained above.
BR,
Adrien
