https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264775 rkoberman@gmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rkoberman@gmail.com --- Comment #1 from rkoberman@gmail.com --- I am seeing a slightly different case that MAY be a similar issue. During a big build, I will often see all CPUs except cpu0 drop from full sp= eed (2101) to minimum (400). This includes the second thread on CPU0, which is clearly nonsensical. The system then cools to about 45C and the fan speed d= rops to 0. At that point, the system stays at 400. I can set CPU0 to 400 an then= to 2010 and all CPUs show 2101, but often the system does not speed up. I test by the trivial technique o building a small port, audio/taglib. It should build in about 15 seconds, but, when the system is running slow it t= akes about 2:08. If the system remains slow, after some long time (many minutes) it will ret= urn to full stream. Clearly, something i really wrong. This has been happening since at least 1= 3.0 and continues to the current 13.1 stable. The system is a Lenovo L15 which = has the problem of locking up when P-States are not disabled. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D253288.
