I tried googling on that text, and only got these two results from the
gmane mail to news gateway. So googling on just cache_open failed gets
me to a number of hits that suggest it's a kernel message. You're not
doing anything with NFS, are you? (Because I saw that error in context
with NFS, but I've never done NFS, and I've never seen this error
before, after running dual core for about 2 months - amd64x2 5200+
cpu).

Are you sure you have no cache? That would be extremely strange. Is
your cpu a Pentium M or a dual-core intel? I would think the latter,
and that definitely has cache. The celerons and durons were cpus that
either had no cache to speak of or very little. I don't believe your
error message (cache_open) is really speaking of the cache on the cpu.

At any rate, cat /proc/cpuinfo in a terminal will tell you how much
cache ram you have.
Mine is 512K on both cpus (amd64x2).

That may be normal depending on what you're doing. If you're running
multiple cpu-intensive tasks, or running apps that are designed to use
both cores, then you'll see each core more or less equally utilized.
