Yes, ACPI enumerates Host-PCI bridges, and trying to enumerate them w/o ACPI is a bit of a guessing game. > So it appears to me that by disabling ACPI in an attempt to bypass the > QUAD CPU problem, we are causing another issue behind the scenes. > > The root of the problem now appears to be, that if we have anything over > 1 CPU, directly after the kernel is loaded (when booting from the CD), > we receive the error message "panic: madt_probe_cpus_handler: CPU ID 38 > Too High". The moment a second CPU to the machine....it bombs out. You can use 'set hint.apic.0.disabled=1' for now to keep ACPI and just disable SMP for now. -- John Baldwin _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
