I'm having this issue too, with x86-64 Lucid.
I'm on a 1.83Ghz Core2 Duo with 1.5gigs of ram, 2 gigs of swap, and a
fast SATA hard drive.
This feels very much what would happen with an old computer when DMA was
disabled... but of course this is a SATA hard drive, and I don't know
how to confirm if it's configured properly.
It's plenty fast after a reboot, but at some point, it just gets barely
usable. At apt-get upgrade will generally trigger it. Once it's there,
it seems like a little hard drive IO and CPU just don't mix any more (as
if DMA was disabled)
