https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219913 Bug ID: 219913 Summary: emulators/virtualbox-ose-kmod: when MAXCPU option is not default for running kernel 'kldload vboxdrv.ko' will result in kernel panic Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: vbox@FreeBSD.org Reporter: avos@freebsd.org Assignee: vbox@FreeBSD.org Flags: maintainer-feedback?(vbox@FreeBSD.org) Due to ABI difference (vboxdrv passes cpuset_t parameter (bitfield with CPU_SETSIZE -> MAXCPU bits) into smp_rendezvous_cpus()) kernel panics with "ncpus is 0 with non-zero map" message. Manual "opt_global.h" inclusion from current kernel build into src/VBox/Runtime/r0drv/freebsd/mp-r0drv-freebsd.c seems to fix this issue w= hen MAXCPU is overridden; kern.smp.maxcpus may be used instead (in case if other 'global' options are not so problematic). --=20 You are receiving this mail because: You are the assignee for the bug.=
