Bug Description

I've recently upgraded my work laptop from Hoary to Breezy, it's a Dell Inspiron
8200 with 1GB RAM, nvidia graphics at 1600x1200. I've not altered any configs
though I did try installing nvidia 3d drivers in Hoary but they didn't seem to
take effect.

The problem I have is periodically, at its most frequent every 5 seconds or so,
to not happening for 30 seconds or so, the machine freezes, then comes back
again. The keyboard and mouse stick until it unfreezes. The freeze lasts for a
second or two.

There are no messages in /var/log/messages to indicate anything suspicious, and
turning acpi=off doesn't help.

Does it help if you boot the old kernel? It should still be present and
available from the GRUB menu.

Please attach dmesg output from both kernels

Yes booting from old kernels 2.6.10-5-686 and 2.6.11-1-686 are both fine, when I
go back to 2.6.12-8-686 the problems start again. I can find an error that is
produced whenever the freeze happens - if I switch to a text console just before
it freezes, the following is echod to the console:
cpufreq: change failed with new_state 1 and result 0

Looking at my frequency monitor applet, I can see that the freeze co-incides
with the CPU stepping down from 1.8 GHz to 1.2 GHz (the two speeds my machine
operate at).

I have attached dmesg outputs from old and new kernels as per your request.
