It seems we didn't run this test on scobee-kernel with J-realtime before, so it's a bit difficult to determine if this is caused by the recent LTP fork update [1].

Test failed with timeout:

I tried to test this manually on scobee-kernel, but I found this is a bit flaky. In some attempts this test can finish with 10 seconds, but sometimes it will take up to 90 seconds.

Maybe bumping the timeout multiplier can be a possible solution.
