I have just reinstalled OS 11.2 but this time the 64bit system variant. I installed the real-time kernel and saw that the apparmor module reported an error and wasn’t loaded. I have never looked into apparmor and only knows it has something to do with security, and thus I wonder if it is important to do something with this issue? I plan to use the kernel-rt and have more or less always used a variant of this kernel flavour, often self built. Though I can not recall having seen that error before and I have not used a 64bit system before.
If you don’t use it I’d not worry too much. You need to tell the system to use it if you want it. Since you are using the RT kernel there may be a conflict. Also since you reinstalled 64 bit over a 32 bit maybe something did not like that. Did you do a clean install or an update? If update old thing from 32 bit may be left behind.
Hei, thanks for your reply.
I did do a fresh installation so it should not be any problems there. I later discovered some other issues with the system and I suspect they are related with the kernel as well. One of them had something to do with a debugging option which was enabled and which could cause latencies, there was a filed bug report on this; another one was about something I did not understand and the last was just the fact that the system performed poorly with audio. All was probably solvable but I’m not keen on any challenge now, I have just got a new computer after the last one broke down and just want a system that (hopefully) works. 32bit worked quite well before so I gave up the 64bit system.
