Hi: I have multiple problems related to APCI and the ICH6 bus on a Sony VAIO:
- A standard setup doesn't work, having enabled both ACPI and APIC the system grinds to a halt with CPU 85% on interrupts. Disabling APIC solved the problem. - APCI with all enabled causes the system to be unstable and crash hard: No panic, no page fault, no kernel dump or other debug. Disabling pci_link and the system becomes stable. Yet stuff doesn't quite work out of the box: - USB doesn't work, simple stuff like usb mouse or usb keyrings are not found if inserted after boot, and does not work properly if inserted before. - The cardbus devices are created, inserted card is not found although works fine on my other laptop. - The wireless (Intel 2200BG) causes an interrupt storm when configured, and then fails - it was solved setting interrupt in loader.conf. Since this stuff is so buggy, it seems I have to configure everything by hand :( and I really need some hints or techniques on how to guess things right. I have tried enabling debugging, built a GENERIC kernel with extra debugging enabled and building the acpi.ko with debug enabled as described in the handbook. I see a lot of GPE event related errors - but have no clue as to what causes these or how to solve them. The handbook mentions how to dump the existing ACPI tables and ASL and load custom tables - so in theory I should be able to modify and fix it - but it gives no clue to the magic within. Any hints? Also, if I have to set hardware parameters manually for all devices, are there any technique to "guess right"?
