Dear release team,
[ Reason ]
One of the BIOS images in Bochs is built for the default GCC
architecture, rather than the expected i386. This causes the BIOS to
crash, making some configurations unworkable. See #1082917 for details.
[ Impact ]
Some configurations crash the emulated environment.
[ Tests ]
I’ve reproduced #1082917 and verified the fix; the reporter has
confirmed the fix on Debian 12 too (using the updated BIOS image with
the bookworm package).
[ Risks ]
This aligns the Debian build with the upstream build. Only one file is
affected; it doesn’t work currently, and works with the fix. I don’t
see any downside.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable
[ Changes ]
This sets -march=i386 when building the “latest” BIOS image, to ensure
that the generated code works on emulated 386 CPUs.
[ Other info ]
Nothing I can think of.
Regards,
Stephen
