Scanner after hibernation/suspend

[Roken]

OK, it took me an age to get hibernation and suspend working (there's an obscure BIOS setting on my MB that I'd never given a second though to, until I decided to change it "just for fun")

So anyway, now both work a treat, and I have the joyfulness of being able to shut down in a blink, and restart in another blink (STR is lovely).

From a cold boot, starting xsane is simple and quick, but if I start it after a resume it takes a good five minutes to detect the available devices (the devices it detects are the scanner, webcam, and one of my TV cards). The scanner is the scan part of an HP C4180 MFP. The printer works immediately after restart. I'm guessing that the problem is related to V4L2, and my reasons are twofold:

i. V4L devices generally have proven to be a little flakey after a resume
ii. I'm having to use a patched kernel in order to get my TV cards working at all. Having said that, I'm not convinced the patch is the problem since the same issue manifests itself on a .36 kernel which doesn't need the patch.

So the question is, is there anything I can do to resume with these devices good to go right away. It defeats the object somewhat if it takes longer to re-initialise devices after resume than a cold boot takes in the first place.

Are you using bttv? After a cold boot, before you suspend, do a 'rmmod bttv' then suspend. After resume check your devices, and go ahead and do a modprobe bttv.

What patches are you applying for your v4l device?

[the3dfxdude]

Even if you don't have a bttv card, you still have a v4l tuner device. I think there is plenty in common in our hardware and having flakiness in v4l devices. I have a Gigabyte MA-770T-UD3P motherboard, with a Radeon 4670, Phenom II X4, a v4l tuner and have issues on resume and also noticed this is a regression from 2.6.37-rc1 and later. Can you share your loaded modules, lspci -v, and your kernel config so that I can narrow down where to look next?

This went by the wayside for a while, owing to a number of other more pressing issues, so I hope you are still around.

Anyway, we can rule out the v4l patch as being the source of the problem. I'm currently running a 3.0.1 (self build) kernel and the patch isn't required from 3.0.0. Nor am I using bttv, so that rules that out too.

The problem does, however, still exist. Output of lspci is as follows:

And my .config file for the kernel is attached. This is likely a little different than my earlier kernel builds owing to evolution of the kernel itself, but nothing that should make any difference to this issue.
