Hi,
I tested rt-tester with mainline 3.8.0 kernel and
the kernel scripts/rt-tester/t4-l2-pi-deboost.tst failed at

T: prioeq: 0: 82
The current T0's prio is -21 so it failed.
Reading source code, it should be 82 as T2 is at prio 82 and
T0 owns the L1 and T2 is waiting for the L1.
Can I ask
1.is the rt-tester test only for preempt-rt kernel?
No
2.any idea why it failed?
No
It would be nice if you could figure out whether that's a failure of
the test case or a failure in the kernel.
For the whole check-all.sh t4-l2-pi-deboost.tst is the first test case
which failed and in t4-l2-pi-deboost.tst: that line is the first "test"
failed.
I didn't see any failures in the kernel.
But I will spend some time to debug around and get familiar with
the rt-mutex code.
thanks,
yao
