Dist-Upgrade results in 100% CPU on one core

wilberfan · 2012-06-19 01:42:23

Dual-core, 32-bit Intel machine. Did an -Syu two nights ago. A dozen or so packages upgraded--including (I remember) the latest nvidia (302.17-1).

When I first boot-up, I get 100% CPU on one of the cores. htop reveals that it's the X session that's running away (?) Rebooting seems to take care of it--although I don't understand why yet...

Anyone experiencing this--or have any suggestions on what I could look at to see what the problem might be?

Thanks in advance...

I'm experiencing something similar, actually. In my case, though, the problem is mandb... which is ridiculous, it shouldn't need to run as long as it is, even for a full update. I made a thread for it here. If it turns out we have the same problem, I might want to delete my thread.

I had this problem with mount. In fact asking the system for shutdown would set a live lock on a mount process taking one core.

I have had to downgrade the kernel as I also have the maxed out core, with top indicating it is the 'mount' process running at 100% on one core.

There have seemed to be a lot of different misc. issues related with the 3.4.2 kernel, but from what I've seen on the forums and in my own experience, the most recent kernel update to 3.4.3 seems to have fixed most of these. Try 'sudo pacman -Syu' again, and see if that fixes your issue.

Yes, I agree that upgrading to 3.4.3 seems to have solved the problem. :-)

[edit] (Spoke too soon. See post below.)

While everything was fine earlier today after upgrading the kernel, when I booted just now the 100% CPU problem occurred again. I had to reboot a 2nd time...

For now I've added kernel and kernel sources for ignore packages in pacman.conf too many problems to tackle on each update.

Another upgrade and now I have the 100% CPU problem with every boot. (Up to 3.4.4-2 kernel)

I had to downgrade 2 or 3 kernel versions. Yikes.
