On: Those Win9x Crashes on Fast Machines

Do drivers or other kernel code still have this kind of delay loop in current operating systems, or is everything interrupt-driven now?

I thought that was the point of BogoMips https://en.wikipedia.org/wiki/BogoMips

If they need to wait in atomic context, they probably do.

e.g. for linux: https://www.kernel.org/doc/Documentation/timers/timers-howto...

ATOMIC CONTEXT: You must use the delay family of functions. These functions use the jiffie estimation of clock speed and will busy wait for enough loop cycles to achieve the desired delay
