[Bug 665796] Re: Timer interrupt freezes, system becomes sluggish

[Adam Ziegler]

Redirected here from ServerFault and bug 658649 (thanks JRavasi).

Same CPU/video card, although for me the timing is closer to 1-2 minutes
of lockup.  Unlike the original report, though, this seems to happen
without _any_ apparent cause - even if the system is completely idle,
there will be occasional bouts.  Swapping to full terminal via
Ctrl+Alt+Fx will take some 10-15 seconds, but once in terminal,
responsiveness is okay.  top/htop updates at this point mimic stuttering
seen in the GUI.

Again, started happening after a fresh install of 10.10.  Various other
issues raised in relation include nVidia drivers and desktop effects,
neither of which have solved it.
