For many people, it works flawlessly and is mandatory for their hardware to work at all. Unfortunatley, the ACPI spec is often abused by the BIOS authors and our implementation cannot work around all of the literally *hundreds* of different broken BIOSes. The best thing to do here is to send John Baldwin the verbose dmesg output both with and without ACPI, along with the output from the mptable and acpidump commands. In any case, I specifically wrote the 'beastie' bootloader so that disabling ACPI would be easy for these kinds of situations. > 3) The UFS1 file system super block summary data incompatibility (with > FreeBSD 4.9) is still a problem. Please refresh my memory on this problem, I thought that all-known UFS incompatibilities had been dealt with in some fashion. Scott
