With KMSAN enabled (no other sanitizers selected) kernel v6.11.1 doesn't boot at all. It gets stuck at UEFI bootscreen stating that it will load the kernel image, but after that nothing for several minutes... Without KMSAN the kernel boots just fine.

Machine is a Ryzen 5950X with 32 GB RAM and a Radeon RX 6700 XT. Same issue also with clang-18 and/or kernel v6.10.11.

Attached please find kernel dmesg (without KMSAN enabled) and the v6.11.1 kernel .config.

I reduced my kernel .config to check whether some of my .config options might interfere with it.

At one point I got it running but with KMSAN the system is unbearably slow. It took nearly 1 min to get from the UEFI screen to the dmesg listed on the console.

Nevertheless one step further. But I still can't boot into the system with KMSAN enabled as I now hit this page fault as soon as USB gets loaded:
