Does acpidump work ok on 5.4? "acpidump -t -d" stops after 31 lines and says, "acpidump: FACS is corrupt" on stderr. See http://home.hiwaay.net/~dkelly/opus-acpidump-d-t.txt "acpidump -d" runs without error and emits 2754 lines. See http://home.hiwaay.net/~dkelly/opus-acpidump-d.txt ACPI worked with 5.4 so I never had a reason to acpidump then. Could I boot a 5.4 CDROM to test ACPI? Without much effort have put my hands on a "5.3-RELEASE Live Filesystem" CDROM that should make a good test. There was an issue briefly with ACPI in 5.0 or 5.1, very likely in a prerelease. Absolultely certain ACPI worked prior to 6.0 because among other things ACPI installed a power button handler which performed a clean shutdown (same as ctl-alt-del) rather than brute force yank-the-plug crash. > > Oh, and apparently the dmesg buffer isn't big enough to hold > > everything "boot -v" wants to say.

I can work the problem both ways tonight when I can put my hands on the physical machine. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
