 |

Well... it is my entire fault ! I should have taken care 
However...
Your help would be... helpful ! 
1/ Running CFS + RT_PREEMPT, I have been facing once a day https://bugs.gentoo.org/show_bug.cgi?id=347985 that I reported some times ago. (Jack crunching nearly all ressources after a certain time)
2/Of course, I have the following settings as part of my /etc/security/limits.conf : | Code: | @audio - rtprio 100
@audio - nice -10
@audio - memlock 3000000 |
3/ Under CFS + RT_PREEMPT, this was not that much of a problem. Despite very slow displacement, my mouse was still moveable... and... at least... Ctrl-Alt-F1 still functional so that I could ps and kill jackd under console.
4/ I switched to ck-sources. BFS now rules my system... and... definitely does not like this bug :
- Even Ctrl-Alt-F1 is inefficient !
- Even shutdown cannot be launched by hitting the power button.
=> Hardware reset forced ! 
Is there a way to work this around ? that is, under BFS, to be able to kill an application that crunches all ressources.

| The only other option I can think of is to use magic sysrq, e.g. alt+sysrq+k to kill every process running on the current TTY. |
