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 ?
Suspend to RAM resume hangs on a tickless (NO_HZ) kernel http://bugzilla.kernel.org/show_bug.cgi?id=9275 Kernel: 2.6.23 This is HP notebook nc6320 T2400 945GM

I *still* get very slow resume-from-RAM quite often here (new in 2.6.22 kernel, wasn't there in early 2.6.23-rc*).
Hmm. Which one 22 or 23 ?
Something eventually times out after a minute or so and it comes back. Cannot make it happen reliably, unless I'm in a hurry to get something done. :) I suspect USB here, probably the same loopy bug that we added a "loop limit failsafe" for back in 2.6.21(?).
Do you have a pointer to that please ?
