Bug Description

On 5.15.0-1021-nvidia-tegra-igx-rt, the procfs test hangs on both AGX and Nano. This will trigger a reboot from the watchdog timer. Previous test runs have failed procfs with a null ptr deref, but this is the first occurence of a hang that causes a sut-test failure.

I ran the entire ubuntu_stress_smoke_test suite locally on the affected kernel (excluding procfs) and all the other tests were successful. Since this test was already failing, I'm going to hint this occurence as I don't believe it should block the release, but this should be investigated further.

Similar rt_mutex issue with ubuntu_ltp.read_all_proc on -rt kernels. 1022 has panic, 1023 immediately reboots due to WDT failure. Attached log for both.
