Bug#1029270: linux-image-6.1.0-2-686-pae fails to boot in qemu

[Johannes Schauer Marin Rodrigues <josch@debian.org>]

Hi,

I investigated this a bit more and can confirm that this worked:

linux-image-6.1.0-1-686-pae 6.1.4-1

while this one does not:

linux-image-6.1.0-2-686-pae 6.1.7-1

To figure out where the regression comes from, I built 6.1.7 from
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git with the kernel
config from /boot/config-6.1.0-2-686-pae. Strangely enough, I was *not* able to
confirm the bug. So I applied the quilt patch series from src:linux (= 6.1.7-1)
on top and tried again. Now I saw the same output that Helmut posted.

I tried the same with tag 6.1.4 from linux.git and the Debian patches and the
problem did not show. So I bisected between 6.1.4 and 6.1.7, always applying
the quilt patch series (which did not change between these two versions).

If I did not make any mistakes, the following commit introduced this
regression:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=92b0051217f23cba7541d6c4ecbca026477fb642

I can confirm that if I rebuild 6.1.7 with that patch reverted and the Debian
patches on top, the error is gone.

Does that seem plausible?

Thanks!

cheers, josch
