TICKS_PER_SEC is now a fixed compile-time constant for all builds, and is independent of the underlying clock tick rate. We choose the value 1024 to allow multiplications and divisions on seconds to be converted to bit shifts. TICKS_PER_MS is defined as 1, allowing multiplications and divisions on milliseconds to be omitted entirely. The 2% inaccuracy in this definition is negligible when using the standard BIOS timer (running at around 18.2Hz). TIMER_RDTSC now checks for a constant TSC before claiming to be a usable timer. (This timer can be tested in KVM via the command-line option "-cpu host,+invtsc".)

The current implementation of linux_currticks() ensures that the first call to currticks() will always return zero; this results in identical random number sequences on each run of iPXE on a given machine. This can cause odd-looking behaviour due to e.g. the reuse of local TCP port numbers. Fix by effectively rounding down the start time recorded by linux_currticks() to the nearest whole second; this makes it unlikely that consecutive runs of iPXE will use the exact same RNG sequence. (Note that none of this affects the cryptographic RNG, which uses /dev/random as a source of entropy.)
