Hello Christophe, The following commit is responsible for the boot issue.
2997876c4a1a5864baa13d7393c2b68cf5b51183 powerpc/32: Restore clearing of MSR[RI] at interrupt/syscall exit I don't think the commit is faulty. Could you please check my kernel config and the serial log? - https://github.com/chzigotzky/kernels/blob/main/configs/e5500_defconfig - https://github.com/user-attachments/files/24035394/Kernel_6.19.0_Cyrus_Plus_board_P5040.log Maybe, the kernel config isn’t correct for the kernel 6.19. Thanks in advance, Christian
