Even then, isn't it fairly trivial to hang the bus on common PC
architecture?

Certainly a lot of hardware has bugs/misfeatures whereby it can be convinced to grab the bus and never let it go: again, graphics cards are the most common crashers. Graphics card interfaces always seem to me to have been written by madmen, from state machines where if you don't do exactly the right thing the bus locks up, through write-only memory locations, to entire undocumented languages on modern cards...

I remain impressed that Dave Airlie and the other free software graphics cards retain their sanity. I'm sure I wouldn't.

Um, the other free software graphics card *hackers*. As far as I know you can't buy Dave on the high street yet (and I'm not sure how fast he'd be able to do 3D rendering).

(I'll, um, blame it on the weather. I was warned that `high winds and heavy rain are forecast and this will disruption', so presumably as well as disrupting their grammar it's disrupted my posts.)
