What? How do you make the leap from lockdep output on boot to my experience of slow interactive response? > Also this patch was actually for 2.6.20 and you seem to have applied it to > 2.6.21-rc2. I haven't even checked that it cleanly applies to that kernel. It doesn't, a one line fix from Ingo conflicts (and a comment that was changed). 7355690ead6d61f6344072ae61060f985060da29 [PATCH] sched: fix SMT scheduler bug 72fd4a35a824331d7a0f4168d7576502d95d34b3 [PATCH] Numerous fixes to kernel-doc info in source files. I have reverted your patch and the laggy behaviour remains when running glxgears (in fact it seems a bit worse), I don't know about the thunderbird lag while typing since I can't easily reproduce it but I don't recall it ever happening before. So, your patch isn't the cause of a serious slowdown when running glxgears in the background (although it doesn't improve the situation much). It looks like it just slows down X in general rather than using much CPU. -- Simon Arlott - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
