The amd64 install CD boots just fine, installs just fine. After the install, the /bsd kernel panics with a stack trace looking like this (hand retyped): [...] acpiprt5 at acpi0: bus -1 (PCI9) acpicpu0 at acpi0uvm_fault(0xffffffff80c9e980, 0x0, 0, 1) -> e kernel: page fault trap, code=0 Stopped at acpucpu_getpss_0xbf: movq 0(%rax),%rdi acpicpu_getpss() at acpicpu_getpss+0xbf acpicpu_attach() at acpicpu_attach+0x154 config_attach() at config_attach+0x11b acpi_add_device() at acpi_add_device+0x95 aml_walknodes() at aml_walknodes+0x6e aml_walknodes() at aml_walknodes+0x41 aml_walknodes() at aml_walknodes+0x41 acpi_attach() at acpi_attach+0x45d config_attach() at config_attach+0x11b bios_attach() at bios_attach+0xb7 end trace frame: 0xffffffff80d99d80, count: 0 ddb{0}> and at the ddb prompt the keyboard doesn't work. It's USB only on this machine. If it stop the auto boot and boot the /bsd.rd from the monitor it boots happily, though it then offers an install:-( How do I troubleshoot this? Is ACPI a problem, and can I avoid that subsystem? Are there "command line" options I can supply the booting kernel? _Why_ does the install CD install a kernel that doesn't cope with the machine while the bsd.rd kernel that it also installs obviously does?
