For example, if I try "disable > acpi" it will stop at "no event timer available". Here is something similar ... http://forums.freebsd.org/archive/index.php/t-32423.html ... "When I enabled verbose boot logging, the boot seems to hang up just after the kernel load. I have tried disabling ACPI and APIC with the same results. Here is where the news starts to turn good. I tried a FreeBSD 9 disk and got much further. Then, I was either getting a page fault or panic: no usable event timer found depending on boot options. The release errata then set me straight. With debug.acpi.disabled="hostres" I was able to boot! ..." Here is the related errata: http://www.freebsd.org/releases/9.0R/errata.html ... "[amd64, i386] FreeBSD 9.0-RELEASE includes several changes to improve resource management of PCI devices. Some x86 machines may not boot or may have devices that no longer attach when using ACPI as a result of these changes. This can be worked around by setting a loader(8) tunable debug.acpi.disabled to hostres. To do this, enter the following lines at the loader prompt: set debug.acpi.disabled="hostres" boot Or, put the following line into /boot/loader.conf: debug.acpi.disabled="hostres" ..." Anyway, regardless of this attempt, file a PR# for 9.1-BETA1. jb
