https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244705 Bug ID: 244705 Summary: /usr/src/sys/x86/x86/tsc.c: System Clock is 0.3% slow since r352684 Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: theron@freebsd.org Created attachment 212294 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=212294&action=edit reverts the breaking change After switching from 12.1-RELEASE to CURRENT I noticed audio driver appeared to be consuming samples too fast by about 0.3%. However after verifying audio devices are working properly I discovered that system clock is actually slow by 0.3% (confirmed by using ntpdate to compare with time server). This is not a hardware fault since I can reliably get correct clock by booting 12.1-RELEASE or CURRENT r352683 but slow clock with CURRENT since r352684 unless reverting that change. hw.model: Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz. -- You are receiving this mail because: You are the assignee for the bug.help
