Bug#1018060: linux-image-5.18.0-4-686-pae: crashes right away in switch_to_asm



Package: src:linux
Version: 5.18.16-1
Severity: important

Dear Maintainer,

I'm usually running Debian stable on my Thinkpad X30 (a 2003 laptop
with a Pentium III CPU) but I also regularly try out Debian testing on
it to try and make sure I detect breakage before the next release.
This is one such breakage:

Debian testing seems to work fine with the 5.10 kernel from Debian
stable, but when I try to boot with the 5.18 kernel from Debian
testing (i.e. `linux-image-5.18.0-4-686-pae`), I get a kernel panic
right at the start (the timestamp says 0.3s after the start).

I'm not able to copy&paste the message I see on the screen, so I took
a photo instead (sorry).  There you can see one of the lines says:

    [0.3<something>] EIP: __switch_to_asm+0x43/0x5c

which suggests the kernel panic happened because of a problem in
__switch_to_asm.  I'm running the `...-686-pae` kernel usually (since the CPU
is a Pentium III), but just to be sure, I tried the `...-686` version for
older CPUs (i.e. `linux-image-5.18.0-4-686`), and got the same kernel panic.


	Stefan


PS: BTW, while I'm here I should mention that Buster is the best release
of Debian for this machine so far.  The previous best was a long time
ago, just before the switch to KMS (which introduced various regressions
on this hardware, some of which were only finally addressed in Buster).
So, congrats and thank you!
