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. >> 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 > No response from developers .. 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*). 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(?). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
