For future releases, would it be possible to have a desktop kernel and a server kernel? Can PREEMPT help here without changing the HZ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The issue for me is audio. PulseAudio does not work reliably in glich-free mode - latency is way too high. Also the jack audio server is barely useable for me on 11.1. Interestingly jack worked reasonable on 11.0. I am playing with latencytop right now, but I have to figure yet how to interpret the values. This is shown in the upper part: Cause Maximum Percentage ATA/SCSI disk ioctl 77.2 msec 1.9 % Scheduler: waiting for cpu 66.6 msec 28.4 % Executing raw SCSI command 21.7 msec 26.7 % Writing buffer to disk (synchronous) 20.0 msec 0.3 % opening cdrom device 6.4 msec 5.6 % Waiting for event (select) 5.0 msec 16.3 % Waiting for event (poll) 5.0 msec 16.8 % SCSI cdrom ioctl 4.1 msec 1.2 % Userspace lock contention 4.1 msec 2.0 % In the lower part I get no listing for pulseaudio or jack. Dunno if they need to be running for a while. For X I get e.g. this: Process X (5105) Total: 503.9 msec Scheduler: waiting for cpu 5.3 msec 79.8 % Waiting for event (select) 4.9 msec 20.2 % -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
