Bug#917569: linux-image-4.19.0-1-686: fails to boot on i386 (Soekris net5501) BUG at arch/x86/mm/pat.c:549
Package: src:linux
Version: 4.19.12-1
Severity: important
Hi!
After upgrading an i386 box (Soekris net5501) running testing (buster),
I found out that the newly migrated Linux kernel fails to boot.
Looking at the boot through the serial console reveals the attached
output, in which I spotted the following line:
[ 5.363599] kernel BUG at arch/x86/mm/pat.c:549!
The previous kernel image (4.18.20-2) works with no issues.
I have temporarily altered GRUB_DEFAULT in /etc/default/grub, in order to
force the box to automatically boot that kernel version.
I hope this bug may be fixed soon.
Thanks a lot for any help you may provide!
