Hello, I am using a Dell Optiplex GXpro. Until recently this machine would not work with : options APIC_IO defined in the kernel configuration file because this machine does not connect the 8254 clock to the IO APIC. As a result you get the following message during boot: APIC missing 8254 connection panic(cpu#0) Recent updates now allow this configuration to work. All you have to do is to uncomment the line : #define IRQ_LO_NC in sys/i386/include/smptests.h. Et voila ! Everything works great after that. Once it is known to be working on several machines it will become the default action. If your motherboard experiences this panic, please report the results of using this option to smp@freebsd.org. I wish to thank Steve Pass for his code and help with this special case. Janick Taillandier
