Yes, it sometimes take some time and specific I/O to trigger the bug.
Sometimes my computer would run for a couple of hours without a problem, and sometimes it would crash within minutes.
You can test it by doing some very heavy I/O on the disk that uses BFQ (maybe until the cache is full and swapping starts).
I'm not sure but it also seems to be triggered faster on NVMe drives (but that's just hypothetical).
EDIT: to actually see the bug report immediately, boot with debug
boot parameter and start in runlevel 3.
It should look similar to the one you see in the kernel thread.
EDIT 2: I haven't looked close enough the first time, you already use "none" for NVMe, so that's fine. I would suggest changing the other two to "mq-deadline" temporarily.
