My Z60t ThinkPad 'idling':

tpb is using more than 25% as much CPU as Xorg (and I'm not mashing on the
volume buttons!). uptime above: 2 days.
I don't recall seeing tpb that high before, but I haven't been looking since I
upgraded from FC6 so I can't be sure when this started happening.
(Sorry for the delay here, I was out of town...)
What arch is your install? i686? or x86_64?
Can you see if the latest update kernel fixes the issue?
Arch is i686. I've updated to kernel-184.108.40.206-41.fc7 (and all other updates)
and the problem is still there.
I also tried lowering POLLTIME in /etc/tpbrc from the default 200000 to 400000
but it didn't seem to make much difference to the CPU consumption, although the
volume buttons often failed to work... :-)
Is there a way to get rid of tpb altogether? I thought I read on planet Gnome
(Richard Hughes?) that the thinkpad extra buttons were supported as ACPI events.
What listens for these events? Is there a package I can install, so that the
polling tpb can be dropped?
Perhaps you mean this post: http://hughsient.livejournal.com/29730.html
If you can bypass tpb that would be a great solution.
tpb seems pretty much dead upstream. ;(
Yeah, that's the one.
So, looks like tpb is dead but HAL will handle this in F8. Groovy.
I guess this bug can be closed?
Thanks for looking!
Sure, I'd be happy to close this... Do you have any way to test and see if you
can get things working with the new setup? I hate to close this without being
sure that it will get solved for you.
Possibly booting the f8test1 live image?
I'll go ahead and close this now.
Feel free to reopen or file a new bug if you see it again...
