Just for those interested: I do *not* get any messages at all from the kernel (or elsewhere) when my mouse goes haywire. And it's an absolute truth (just tested back and forth 8 times) that it *only* happens with SCHED_ULE and *only* with old versions (~1.50) and the very latest ones (1.75 as I'm currently running). 1.69 for instance did *not* show any such problems. I will, however, update my kernel again now, to get the latest sched_ule.c (if any changes have been made since 1.75) and to test with the new interrupt handler. I have a suspicion it might be a combination of SCHED_ULE and some signal/message/interrupt handling causing messages to get lost along the way. Because that's exactly how it feels...
