--- Comment #37 from Thomas Renninger <tr...@suse.de> 2010-11-01 17:43:25 --- vyncere: Your problem is different. Could it be that cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit does not show max freq? Then it is related to: https://bugzilla.kernel.org/show_bug.cgi?id=14771 But in contrast to Peter's problem it's BIOS related (and the root cause may be different and related to ACPI). If above (bios_limit) is true, best update your BIOS, check related BIOS options, if processor.ignore_ppc=1 workarounds and BIOS fiddling doesn't help, please open a new bug and assign it to the ACPI component. Peter: Your CPU (counters: tsc, aperf, mperf) is/are broken. Heinz may have a similar problem and if this is more common, a getavg check could be added whether the values are far away from min/max and getavg is not considered anymore then. As this is a hotpath, this could be implemented in a similar check as TSC is checked at boot up, e.g. test 3 times over 100ms whether getavg is inside ~min/~max limits, if not don't use it. If this normally never happens it might not be worth it and just the module param could be added -> Waiting for a test from Heinz, either the boot param and/or a runtime timer check should be added. -- 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 acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
