System reboots ~10 seconds after I try to suspend/hibernate since 6.16

for the sake of it, I just tried disabling speakers, microphone and fingerprint reader. the issue persists

I also noticed that the issue is still there when running echo mem > /sys/power/state after adding systemd.unit=rescue.target to just boot intoa rescue shell. still reboots after suspending

With this being pretty much guaranteed to be some kernel regression and quite likely just some random side-effect affecting power draw profiles, you'll not get around bisecting the kernel to narrow down on what element is even driving that (and then see what can be done about it)

a live image with a new kernel works fine, which is why I wanted to try out a few other things first, but I guess I'll just try to bisect again..

This is my plan, let me know if I'm doing something wrong (I was previously using a modified pkgbuild, which lead to the tagged commit being the first bad, which clearly makes no sense):

git clone https://github.com/gregkh/linux.git
git bisect start v6.16.1 v6.15.9

and then, on each step:

git bisect good/bad # except on the first one, ofc
zcat /proc/config.gz > .config
make olddefconfig
make -j16 bzImage modules
sudo make modules_install
sudo cp arch/x86/boot/bzImage /boot/vmlinuz-bisect
sudo mkinitcpio -p linux-bisect

I added the following to /etc/mkinitcpio.d/linux-bisect.preset:

ALL_config="/etc/mkinitcpio.conf"
ALL_kver="/boot/vmlinuz-bisect"

PRESETS=('default')

default_uki="/boot/EFI/Linux/arch-linux.efi"
default_options="--splash=/usr/share/systemd/bootctl/splash-arch.bmp"

Pointing towards access on the root partition being *a* factor but that doesn't even mean that the breaking change came from a patch in that area (you're just changing an element of the overall power draw)

You might want to use https://github.com/archlinux/linux/ and v6.16-arch1 / v6.15.9-arch1 instead of Greg's sources
