Subject: [REGRESSION] disabling and re-enabling magic sysrq fails after kernel 6.11
Date: Sat, 26 Oct 2024 19:15:30 -0700	[thread overview]
Message-ID: <Zx2iQp6csn42PJA7@xavtug> (raw)

Hi,

It looks like starting with kernel 6.11, disabling and re-enabling magic
sysrq fails with these errors in dmesg:

kernel: input: input_handler_check_methods: only one event processing method can be defined (sysrq)
kernel: sysrq: Failed to register input handler, error -22

after doing:

# echo 0 > /proc/sys/kernel/sysrq
# echo 438 > /proc/sys/kernel/sysrq
# echo 0 > /proc/sys/kernel/sysrq
# echo 438 > /proc/sys/kernel/sysrq
# echo 0 > /proc/sys/kernel/sysrq
# echo 438 > /proc/sys/kernel/sysrq
