If anyone is volunteering to setup and maintain this sort of thing, I've
been collecting test programs of various sorts and I'll bet lkml has
tons of suggestions.
Unfortunately regression tests in particular aren't plentiful because a
lot of bug reports are handled without specifically creating a test case
which exposes a problem. Also recognize that there are a class of
problem for which creating tests is difficult ("it won't boot when XXX
switch is flippped in BIOS").
