Same warning. Experiments with 6.0-STABLE x86 (so, really, amd64 readers ca=
n=20
switch off) show the following:
1) 6.0-R x86 can be installed if ACPI is switched off.
2) With ACPI off, an interrupt storm will use 97% of CPU or so, so the=20
installation takes a long time. It may be worth digging out a 2x CDROM driv=
e,=20
since I couldn't get a 52x to stay stable long enough to install from.
3) The DSDT is just so totally fscked on this system you need to hex-edit i=
t=20
to fix it. I'll post a partly-fixed DSDT on a website if anyone needs it.=20
This causes checksum errors, but that doesn't seem to bother the system.
4) With the fixed DSDT and TFH "11.16.5.3 Overriding the Default AML" you c=
an=20
boot with ACPI enabled and the interrupt storms will be over.
4a) Fixing the rest of the AML is beyond my ken, since it's got methods use=
d=20
before definition (can I just move them up in the source file?).
4b) If that's fixed, then there's a bunch of If(SS1) statements outside of=
=20
method bodies; SS1 is defined as constant 1 elsewhere, so this looks like=20
it's intended to be conditional compilation, which the current iasl doesn't=
=20
support.
4c) If anyone else feels like looking at the ASL, I'll post it somewhere.
5) I just panic'ed the system while downloading portupgrade and accessing t=
he=20
CDROM drive concurrently, so stability is an issue.
