https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211548 Konstantin Belousov <kib@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kib@FreeBSD.org --- Comment #1 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Benedict Reuschling from comment #0) What exactly the statement 'won't boot' mean ? Does the machine enters infinite loop with the messages ? I would like to see the verbose dmesg with the x2APIC option turned off and= on (can you capture using serial console ?). Can you compile and boot kernel without mps(4) ? You probably would be not able to mount local root, but I need messages and not the operational syste= m. I do not think IPIs are ever used at the device probe stage, so it might be some pecularity in the BIOS resources allocation triggered by the option. --=20 You are receiving this mail because: You are on the CC list for the bug.=
