--- Comment #33 from Thomas Renninger <[email protected]> 2010-10-29 20:15:27 --- I wonder why Heinz has: clocksource=hpet acpi_skip_timer_override Peter's machine has an unstable TSC, that is strange, cpuflags show constant_tsc. So it seems it falls through some boot check to not increment constantly. Hmm, you both seem to have problems with TSC..., aperf/mperf may be fed by the same internal clock as TSC. If average frequency calced via aperf/mperf is very low, the frequency would never get ramped up. It's hard to believe, because you have so different CPUs, but it looks like you both have broken TSC/aperf/mperf timers on CPU 0? At least Peter has? Another patch to try.., please use: acpi_cpufreq.disable_average=1 boot param and check dmesg that it got applied: "acpi-cpufreq: average (aperf/mperf) accounting disabled by user" -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
