https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=284275 --- Comment #4 from John Baldwin <jhb@FreeBSD.org> --- Hmm, a panic without ACPI due to not finding APIC should be deterministic. When ACPI is disabled, we use the MP Table to enumerate APICs. If the table is missing, you will get that panic, if the table is present, you will boot. The fact that you are only getting that panic sometimes is very odd. It means your firmware is not always generating that table. In general though, disabling ACPI is not really recommended on modern systems. The most helpful next step would be getting a verbose boot to better narrow down where it is hanging. -- You are receiving this mail because: You are the assignee for the bug.help
