I am about ready to punt. It almost looks like a hardware problem, but I think you mentioned that it works with other OSs. Might it be something in ACPI is disrupting communication? I have PSD=ACPI.PSD /SMP /ACPI /SAP:0x20.
Chuck,
PMFJI, but...
It's understandable with the similarity, but did you intend the switch
to be '/APIC' instead of '/ACPI' in your settings?
[And, FWIW, as I've said before, '/APIC' caused me serious problems and
no problems w/o it.]
Chuck and I are using identical ACPI.PSD strings, and yes, that should indeed be /APIC (vs PIC mode). Evidently, the T61 has an easier time with APIC mode than the T60.
For everyone's edification, from ACPI-FAQ.doc:
Q33: What is the advantage of APIC mode?
A33: For example,
* Computers work in APIC mode faster than in PIC mode (/PIC) because
of less checkings
* On some computers, if running in PIC mode, all devices are using
one IRQ, this causes troubles.
Disadvantages of APIC mode: * with high IRQ there are problems with old drivers
* there are problems with winos2 --
