Didn't you noticed any of the reports about very bad numbers for latency since Ingo's latest 2.4.17-K3 version? Even Alan's tree show the same (latest I've checked was 2.4.19-pre2-ac2).
We do need some words from Ingo first. He haven't answered my posts since February ;-( But yaybe he didn't got them 'cause I send them to mingo@elte.hu ???
If you run without O(1) latency is like before. You'll get better numbers with preemption+lock-break (ongoing merge of Andrew's lowlatency patches).
But I see some kernel hangs with preemption on UP. It happens only during "make bzlilo" (the linking stage). Robert? Apart from that it works well.
