Some of these are/were still in -mm queue, but since they seem to have been dropped and anyway haven't been merged, I'm resending them anyway. Also, we have one big 2.6.10 regression which is still unfixed: top always shows ksoftirqd/0 as runnable, while it gets 0% cpu time, and loadavg goes then to 1.0, while no real load is generated... Possible culprits could be the IRQ code rewrite, maybe; I've not found what the hell can be arch-specific for this (except that UML does not support PREEMPT and that SMP, and locking in general, isn't well tested yet, even if the biggest problems are just theoretical, luckily). I've not yet had the time to analyze it successfully (but while looking at this I saw the PREEMPT_ACTIVE problem, which also extends to other archs, see my other mail). -- Paolo Giarrusso, aka Blaisorblade Skype user "PaoloGiarrusso" Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ___________________________________ Yahoo!
