Yeah I imagine reverting patches from kernel 2.6.32.10 up to 2.6.20 and seeing all these conflicts in git.
I have just done this in different way: downloaded official 2.6.32.10 and manually reinserted the removed code.
I resolved IRQ_DELAYED_DISABLE irq.h conflict by moving it to higher bitfield position.
The patched kernel booted OK but these reverts did not resolve the OHCI hangs in APIC mode.
The final verdict is: idea #1 was false.
Now I focus on #2 and #3 ideas.

Call for action:
1. If you have any idea why ohci hangs in APIC mode let me know.
2. If you have Nvidia MCP78S mainboard with AMD CPU please send me ACPI dump:
acpidump > dump.bin
bzip2 -9v dump.bin
This will be good APIC code comparison to check the #3 idea.
Do not mess the ML with attachments - send me the file(s) PM.

On my mainboard almost all onboard devices are sitting on INT A according to ACPI code.
Only USB 2.0 EHCI controller sits on INT B alone.

have a nice day,
Zbigniew Luszpinski
