https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D284275 Bug ID: 284275 Summary: Jingsha B85M-I: System hangs on boot unless kern.smp.disabled=3D1 Product: Base System Version: 14.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: k4sum1@eclipse.cx Created attachment 256916 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D256916&action= =3Dedit Boot screen at freeze without kernel panic System is a custom built PC with a Jingsha B85M-I mainboard and an i5 4570T CPU. Booting in CSM/Legacy/MBR mode will result in the system hanging at bo= ot. UEFI mode is significantly more reliable, booting more often, but it still, albeit rarely, can freeze at the same spot. (I've only seen this twice with UEFI boot) Sometimes I get a kernel panic, but most of the time it just han= gs there. If I set kern.smp.disabled=3D1 the system boots up just fine. The system just reboots if I boot without ACPI, the first few times it then successfully booted without any changes, but I haven't been able to replica= te it again. Only one time booting without ACPI I got a kernel panic of "runni= ng without device atpic requires a local APIC" If I reset the system instead of powering off then back on after a failed b= oot, it will sometimes successfully boot, however I haven't been able to replica= te that the past few times. I've tested stock FreeBSD 14.2 and 13.3 (XigmaNAS 13.3.0.5), both have the = same issue and the fix is the same for both. --=20 You are receiving this mail because: You are the assignee for the bug.=
