Hello. I have been using a cr21/z laptop which probably has acpi related problems that introduce latency. I noticed it because a recent update in my Ubuntu precise makes my system's clock stay behind, and freezes my laptop when there are no mouse or keyboard actions. Somehow it looks related to https://bugzilla.kernel.org/show_bug.cgi?id=20172 If I boot my kernel with noapictimer clocksource=jiffies irqpoll options the system reacts to my actions instantly. It is the first time that I have exprerience lag free reactions from my system. Unfortunately there are spikes of 100% CPU usage, due to irq polling I assume, which makes my system less power efficient. Is there any case that we can somehow fix this problem? I am using latest git kernel. The same problem also exists in current Ubuntu precise 3.2 kernel. Thank you in advance.
