Thanks, Peter. I'm going to run the regression tests in /misc today.

Yes, that's right.

The primary goal is to crash the kernel. If running the tests for a 
long time does not cause a panic, that is often interpreted as 
"success". A different view is that the test suite is broken :) 

Look at the (regression) tests in stress2/misc, and run them by 
./all.sh -o 

This should take some 36 hours on modern hardware. Remember to add 
a swap disk, as many of the tests rely on VM pressure.
