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? Kalle
