crosstool: x86 kernel compiled with GCC 14.1 fails to boot

[Kalle Valo]

Hi Arnd,

I installed GCC 14.1 from:

https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/14.1.0/

But I have a problem that a kernel compiled with that compiler fails to
boot on my x86 NUC test box. I don't see any errors, just black screen
and I assume after that the kernel either crashes or reboots and goes to
back to the GRUB menu. This loop seems to continue forever. GCC 13.2 and
older from crosstool work just fine.

Do you happen to have any ideas what could cause this or how to debug
further?
