I still think the patch isn't very good. See my previous email. 

The fact that your machine works again is good, though. But before we let 
this lie, I'd _really_ like to know what was broken in the legacy PM path, 
rather than "let's leave it behind". Because a broken legacy path will end 
up biting us for other drivers, and I think the new PM path will need more 
work before it's ready for prime-time.

That's not a devid/vendorid, it's an extended "subsystem" capability that 
we didn't save. We could try to save/restore all capabilities, but right 
now we only do the ones we care about (pcie/pcix/msi, iirc).

I do suspect we might be better off saving everything we can, rather than 
deciding piece-meal to save specific capabilities we know about.

Ok - I will run with it temporarily and will do what I can to track down 
what was wrong with the legacy PM.

Thanks!

If you can try the patch I just sent out, and use that as a base for 
trying to track down why the heck the legacy code doesn't work, that would 
be great. It might fix it (assuming my guess about "restore_state while in 
PCI_D3 doesn't work" was correct), but quite frankly, it's equally 
possible that it just makes things worse. But it would be really 
interesting to hear..

Your machine does seem to be interesting, in that not only does it have a 
PCI-E bridge in it (the eeepc I was playing around with at LCA does not), 
but judging by the lost config state I also suspect that it actually loses 
power during STR.

Which is not at all necessarily a given - I suspect it depends on just how 
the power rails are set up on the motherboard. The fact that PCI-E bridges 
have apparently worked for others implies that your problems don't happen 
for everybody, and may relate to that issue.

Sure - will do.

Not sure what the significance of eeepc is in this case - mine being a 
standard Intel 5400 chipset I would have thought that's the last 
place to look for interesting things!

Do we know this for sure that PCI-E bridges + Suspend have worked for 
others - In this thread at least I think people reported tg3 worked but not 
necessarily with a PCI-E bridge.

Technically, they are PCIe root ports and many systems have network adapters
connected through them (I have two such systems here, but none of them with
tg3-compatible hardware - my tg3 is a PCI device).
