0x000000c0 is irq_masked|fiq_masked. I don't see any relevant changes between 6.0 and 6.1 for this to happen. Joey, any ideas? Olaf, can you bisect? I would start with git bisect drivers/firmware/efi/ rch/arm64/kernel/efi* which should be rather quick. -- You are receiving this mail because: You are on the CC list for the bug.

0x000000c0 is irq_masked|fiq_masked.
Which means __efi_rt_asm_wrapper() or the called efi.runtime->set_variable() forgot interrupts disabled and I don't see how -- I assume the latter did not provided it worked in 6.0. -- You are receiving this mail because: You are on the CC list for the bug.
