[Grover, Andrew]

Andrew,

You still hacking on this?

Just got another bug report (completely different HW) that I think might
be the same problem.

Is there anything more to hack??

The patch looked adequate to my novice eyes.

Hope it gets integrated into the acpi & kernel releases soon

P.S. my ISP is blocking sneakemail e-mail at present, so e-mails sent 
direct to me will probably bounce :-(

Yeah, I've been having a wee break for a few days. back on it now.

Interesting fact. All my onboard devices work now, but I didn't have any PCI 
cards. I've just put a wireless PCI card in my machine, and its having the 
same IRQ problems as I used to with the onoard ones!

I take it that the IRQ polarity issues are now fixed.
The remaining issues are to handle the cases where ACPI routing fails,
and cases where the _SRS method fails?

Once again thanks for working on this.

P.S. Sneakemail still blocked by my ISP, so e-mails direct to me will
most likely bounce.

For me, they seem to be fixed for onboard devices, but not for devices plugged 
into PCI slots. 

I can detect when _SRS fails easily enough as you can do doubt see. What I 
need is a way of reliably dropping back to a different configuration method 
if _SRS fails. On my board, when I hack it to pretend theres been a failure, 
I can't yet get the drop-backed-to mechanism to reconfigure any IRQs which 
were configured with _SRS (even if it fails) properly.
