Thank you, that is an extremely useful tool.

It caught two errors on my EEE, one of which I knew about, and the other was a ttotally new thing to me.

I know my kernel doesn't have HZ=1000, becuase when I do that, it doesn't boot. So, sorry,  no 1000Hz timer.

But it also caught this other weird thing I'd never heard of:
fs.inotify.max_user_watches = 524288

Which was easy enough to fix.

Fascinating. Thanks again!
