Testing log: - turned off all overclocking (even XMP, RAM is 2400MHz now) just to be sur= e, turned off ERMS, basically running stock firmware settings - everything seems perfectly stable on a kernel from September - rebuilt current kernel cleanly (erasing /usr/obj and ccache), unstable - rebuilt it with llvm10, unstable - rebuilt it without CPUTYPE, unstable - rebuilt the exact git revision of the September kernel, fine! --=20 You are receiving this mail because: You are the assignee for the bug.=
