The qemu-i386 boot failed with no console output and is still happening on the latest mainline master branch.

But this is bisected to the mm merge, not the char-misc merge, right?
And is this just on i386? Nothing arch-specific in the char-misc merge that I can see, so I would place bets on mm doing something accidentally on 32bit systems.

The qemu-i386 boot pass with the latest mainline kernel with clang-nightly and gcc-13. Linux version 6.15.0-rc1 (tuxmake@tuxmake) (Debian clang version 21.0.0 (++20250402105505+c57b9c233a87-1~exp1~20250402225526.1363), Debian LLD 21.0.0) #1 SMP PREEMPT_DYNAMIC @1743981563
