Also knowing if a 6.3 bootonly CD shows the same > issue would probably be useful. 6.3 CD had the same problem as well, last I tried. Also DL'd the 8.0 livefs CD from the 200807 directory (8.0-CURRENT-200807-i386-livefs.iso) and it also had the same problem. The latest Linux kernel (that I tried) also has a very very similar problem (I think it was 2.6.18). So it's not something that isn't common throughout the open source OS world. On a related note... I have made the following additional observation and am attempting to prove or disprove whether this is responsible. The ACPI tables list IRQ 9 as being level triggered HIGH, whereas the "no APIC" boot log shows IRQ 9 as being level triggered LOW (assigned by 'atpic'). I do not know whether this is a problem in the ACPI table or the interpreter, but I shall investigate this one further. IRQ 9 (as I recall) affects everything with a higher IRQ number on ISA platforms since if feeds from the 2nd PIC. So if keyboard and serial work ok, but the disk drives do not, that might explain why.
