Bug#1079725: linux: powerpc: 6.9+ kernel fails to boot from Open Firmware with CONFIG_CRASH_DUMP=y
Package: src:linux
Version: 6.10.4-1
Severity: normal
File: linux
X-Debbugs-Cc: dave@vasilevsky.ca
Debian kernels 6.9 and higher fail to boot on most PowerPC 32-bit systems.
These kernels have CONFIG_CRASH_DUMP=y set. This yields the message:
> Error: You can't boot a kdump kernel from OF!
See discussion on the debian-powerpc list:
* Initial report: https://lists.debian.org/debian-powerpc/2024/07/msg00001.html
* Verification that CONFIG_CRASH_DUMP is indeed the problem: https://lists.debian.org/debian-powerpc/2024/08/msg00018.html
This occurs due to a change upstream, that makes CRASH_DUMP enabled by default.
We're working on fixing this upstream: https://lore.kernel.org/lkml/87frqsghws.fsf@mail.lhotse/T/
In the meantime, Debian's kernel config should explicitly disable CONFIG_CRASH_DUMP on
32-bit powerpc.
