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.
