Either the bump from sched_ule.c 1.75 to 1.77 changed something back to the old status, or the new interrupt handling has had some major influence. All I can say is - wow. My system is now more responsive than ever, I cannot (so far) reproduce any mouse jerkiness or bogus input or anything, and things seem smoother. As always I cannot guarantee that this report is not influenced by the placebo effect, but I do feel that it's a very real improvement. The fact that I can start VMWare, Firebird, Thunderbird, Gaim and gkrellm at the same time without having *one* mouse hickup speaks for itself. I couldn't even do that with ULE. So Jeff or whoever did the interrupt stuff - what did you do? /Eirik > > Greetings, > /Eirik > > Morten Johansen wrote: > >> On Tue, 4 Nov 2003, Sheldon Hearn wrote: >> >>> On (2003/11/04 09:29), Eirik Oeverby wrote: >>> >>> > The problem is two parts: The mouse tends to 'lock up' for brief >>> moments >>> > when the system is under load, in particular during heavy UI >>> operations >>> > or when doing compile jobs and such. >>> > The second part of the problem is related, and is manifested by the >>> > mouse actually making movements I never asked it to make. >>> >>> Wow, I just assumed it was a local problem.
