There are two major issues on arm64 Juno-r2 on Linux stable-rc 6.9.6-rc1
Reported-by: Linux Kernel Functional Testing lkft@linaro.org
The LTP controllers cgroup_fj_stress test cases causing kernel crash on arm64 Juno-r2 with compat mode testing with stable-rc 6.9 kernel.
In the recent past I have reported this issues on Linux mainline.
LTP: fork13: kernel panic on rk3399-rock-pi-4 running mainline 6.10.rc3
it goes like this, Unable to handle kernel NULL pointer dereference at virtual address ... Insufficient stack space to handle exception! end Kernel panic - not syncing: kernel stack overflow
How is that related to 6.9.6-rc1? That report is from mainline (6.10.rc3).
Can you share a similar kernel dmesg output from the issue on 6.9.6-rc1?
