Whe= n I activate X2Apic Mode in the processor settings in the BIOS and boot FreeBSD= , I get the following error: http://people.freebsd.org/~bcr/mps0_error.jpg Deactivating the X2Apic option in the BIOS lets FreeBSD boot normally and t= he mps0 controller can use the attached disks normally. I have several (12 in total) systems like these, all exhibit the same behaviour. I can provide more information on firmware versions and other details upon request. --=20 You are receiving this mail because: You are on the CC list for the bug.=
