Comment 27 for bug 657990

This also affects my NB200 running Ubuntu 10.10 netbook edition, updated from 10.04.

I'm testing the 'nolapci_timer clocksource=jiffies' suggestion. So far it has completely fixed the problem of constant hanging. And I can now listen to music on Rhythmbox with no glitches at all (an improvement over my previous 10.04 install, which occasionally stuttered!). This seems to suggest the hanging isn't happening any more.

But now I'm going to test the battery life. Don't see why this particular fix should increase battery use, but it might. Will report.

[later] Update:

Running on battery, still no hangs at all and music running smoothly. As for battery life, it appears to be as good as or better than previously with Ubuntu 10.04 (ie a bit over 2 hours with a 3-cell battery, max charge 22.7Wh, currently at 12Wh or 53% after 1 hour use, according to Gnome-power-statistics). [Can someone please point to instructions for getting better battery life out of NB200 that have worked for them?]

It may be that the bug we're experiencing is one of these (which may be the same bug):
https://bugzilla.kernel.org/show_bug.cgi?id=21032
https://bugzilla.kernel.org/show_bug.cgi?id=20172
If so, it may be fixed in the next release of the kernel.

If this keeps working - hat tip to sfranzyshen.
