Linux 6.2 and newer are (mostly) unbootable on my old HP 6730b laptop, the =
6.1.30 works still fine.
The weirdest thing is that newer kernels (like 6.3.4 and 6.4-rc3) may boot =
ok on the first try, but when rebooting, the very same version doesn't boot=
.
      =20
Some times, when trying to boot, I get this message repeated forever:
ACPI Error: No handler or method for GPE [XX], disabling event (20221020/ev=
gpe-839)
On newer kernels, the date is 20230331 instead of 20221020. There is also s=
ome other error, but I can't read it as it gets overwritten by the other AC=
PI error, see image linked at the end.

And some times, the screen will just stay completely blank.

I tried booting with acpi=3Doff, but it does not help.

I bisected and this is the first bad commit 7e68dd7d07a2
"Merge tag 'net-next-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/=
netdev/net-next"
      =20
As the later kernels had the seemingly random booting behaviour (mentioned =
above), I retested the last good one 7c4a6309e27f by booting it several tim=
es and it boots every time.

I tried getting some boot logs, but the boot process does not go far enough=
 to make any logs.
