https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D275594 --- Comment #66 from Peter Much <pmc@citylink.dinoex.sub.org> --- (In reply to Seigo Tanimura from comment #64) They are from the official distribution 6c2137593990 (plus local fixes): FreeBSD disp.***** 13.3-BETA1 FreeBSD 13.3-BETA1[0d65a8c79a4a=3D6c213759399= 0+27] D6R13V1 amd64 This installation comes from a deploy engine, we're usually not building locally. (To build locally means to start a test case, and to do so I must first get= rid of my currently open test case, otherwise I do no longer know what exactly = was changed where. This is why things proceed slowly here - I usually do root c= ause analysis.) I am mainly worried about the endless loop. An endless loop in kernel thread MUST NOT happen (for whatever reason), because it cannot be contained with rctl(8); it will keep cpu at max and may bring thermal load steering into disarray. --=20 You are receiving this mail because: You are the assignee for the bug.=
