https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219882 --- Comment #3 from John Baldwin <jhb@FreeBSD.org> --- Created attachment 183451 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D183451&action= =3Dedit noassign_on_up.patch Please try this patch instead. In the !EARLY_AP_STARTUP case, the 'assign_= cpu' variable is never set on a UP system, so it results in never trying to assi= gn CPUs. This patch restores that by checking for an SMP system explicitly be= fore trying to assign a CPU. I think the panic in the atpic method is still a g= ood canary for ensuring the calling code is doing the right thing. --=20 You are receiving this mail because: You are the assignee for the bug.=
