No response from developers

The bug report is bogus. ARM has no CONFIG_HPET_TIMER.
Note: that same bug exists/existed on i386 back when NO_HZ was introduced (2.6.21?). I still see it from time to time on my Quad core system (very rare), but not any more on my Duo notebook where it used to happen about 1 in n boots (n < 10).
AFAICT no fix was ever released for it.
Hmm, at which point does the boot stop ?
..
Just as it prints out these messages, sometimes one of them, sometimes both (or all four on the quad core):
kernel: switched to high resolution mode on cpu 1 kernel: switched to high resolution mode on cpu 0
