Plenty of BSOD calls for sure. Also some very memorable calls from a bunch of Linux guys who would think-up of a monster Windows machine loaded with all sorts of crazy hardware peripherals and call support to mess with us.
Are you sure it was truly just to mess with you? If I were a Linux kernel maintainer back then, and there was some hardware I wanted to fix support for but didn't personally have the money to buy, I think "trick Microsoft into divulging how their own driver for it works" would be what I'd see as a "clever hack"!
