I was forced to enable swap because it I run out of RAM without swap then 95% of the time my laptop hard reboots. Adding a ton of swap fixed it.

My next issue is that sometimes it just hard-freezes. Zero warning, under no load, I can't even move the mouse. Linux on the desktop!

You may want to consider fixing the system cache value.

I use lower values than Linus suggested.

I don't see why that would cause lock ups? I'm pretty sure it's just a driver bug. Didn't used to do it but I upgraded the kernel recently and then it started.

Interesting thread anyway - do you know if they ever fixed the defaults?
