If I recall correctly, currently FreeBSD depends on ACPI to detect CPU spec including (S)MP topology. And maybe unlikely, but if your firmware / BIOS allows selecting MPS (Multi Processor Spec.) version, changing it to something others (usually 1.1 and = 1.4 but possibly something more) could resolve the issue (quite old experience = on other OS, if I recall correctly). Lastly, if you've not done, what happenes if you add acpi_ibm_load=3D"YES" in your /boot/loader.conf and reboot? Any differences? --=20 You are receiving this mail because: You are the assignee for the bug.=
