How long does it take to hit this bug?

This is the log which has the best information so far. There is a lot of
noise added by multiple subsystems though, could you try reproducing the
issue, but this time with the following kernel options set as mentioned
below?

# CONFIG_FTRACE is off
# CONFIG_KASAN is off
# CONFIG_JUMP_LABEL is off
# CONFIG_EVL_DEBUG_WOLI is off
CONFIG_PROVE_LOCKING=y
CONFIG_DEBUG_HARD_LOCKS=y
CONFIG_EVL_DEBUG_CORE=y

Thanks,

Philippe.
