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.
** Summary changed: - ubuntu_stress_smoke_test.procfs hangs with realtime flavour (AGX, Nano) + ubuntu_stress_smoke_test.procfs and ubuntu_ltp:read_all_proc panics with realtime flavour (AGX, Nano) ** Attachment added: "read_all_proc_panic-1022-rt.txt" https://bugs.launchpad.net/ubuntu/+source/linux-nvidia-tegra-igx/+bug/2103748/+attachment/5871696/+files/read_all_proc_panic-1022-rt.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-nvidia-tegra-igx in Ubuntu. https://bugs.launchpad.net/bugs/2103748 Title: ubuntu_stress_smoke_test.procfs and ubuntu_ltp:read_all_proc panics with realtime flavour (AGX, Nano) Status in linux-nvidia-tegra-igx package in Ubuntu: New Status in linux-nvidia-tegra-igx source package in Jammy: New 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.
