P.S.
Sorry, Paul, the patches did not apply on the mainline "master" or "v6.1-rc5" nor "v6.0.9".
Here is the session log:
mtodorov@domac:~/linux/kernel/linux_stable_build_b$ git checkout v6.1-rc5 Note: checking out 'v6.1-rc5'.
You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example:
git checkout -b <new-branch-name>

Now I really got to try to catch some sleep because I work my day job in the morning.
I must admit that I am not enthusiastic about these patches for I think they only mask the problem of stalls: removing reports from the logs, but cores will still lock up.
Besides, I also hoped to develop multimedia for Android devices, too, as a part of our research, to academically justify my work on the Linux kernel bug bisection and learning about the kernel proper.
I still need to figure out a way to present my results to the academic community, to have it justified and to have our University more visible and ranked on the world list. ;-)
Thanks, Mirsad
