No need to modify the system pm scripts; it has support for this sort
of thing built-in.  Create /etc/pm/config.d/defaults with this line:
  SUSPEND_MODULES="forcedeth"

Obviously this is just a workaround until a real fix goes into the
kernel, but it should do what you need for now.

I didn't know that, sorry.

Basically, you can do:

$ git whatchanged v2.6.28..v2.6.29 drivers/net/forcedeth.c | grep '^commit'

Unfortunately, after moving to a different appartement last weekend,
my nforce mainboard is now about 650Km from where I am and will stay

Not so easily :/ I don't know git for start, what I did so far was through the 
web interface, but this morning a lot more commits appeared so my assumption 
that if I start by selecting 2.6.29 tag and then tree, that leaves the view 
in 2.6.29 tagged state was obviously wrong.

What I managed to do is to revert this:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=34edaa88324004baf4884fb0388f86059d9c4878

But that didn't fix the problem. That one was also the last commit yesterday, 
but not any more today as I said. Interestingly, the next one 
(http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=e70049b9e74267dd47e1ffa62302073487afcb48#patch203) 
seems to introduce the same change.

Anyway, I won't have time due to personal and business commitments to test 
this further for a couple of weeks.

Well, since you can easily check what commits changed forcedeth between
2.6.28 and 2.6.29, you can find the one that introduced the problem for you.

Good idea, I had to massage it a bit due to some API changes, but the end 
result is a correct resume which proves that the problem really is in 
forcedeth.

Actually yes. Testing forcedeth from 2.6.28 in 2.6.29 would be nice
way to prove problem is indeed in that module.

Not a lot activity in forcedeth.c from 2.6.28 to 2.6.29 so I will CC two guys 
who commited changes in that period. Ayaz, Tobias, forcedeth does not seem to 
come up after hibernation well for me. Actual hardware is:

00:0f.0 Ethernet controller: nVidia Corporation MCP73 Ethernet (rev a2)

Anything more I can do just shout!

I have a box with forcedeth somewhere here, I should be able to check that
in the next few days.

Ok, I guess you need to talk to forcedeth maintainers then... sounds
like a forcedeth problem to me.

Sure, after insmod and /etc/init.d/network start following resume network was 
fine. Guess I could kludge that sequence into pm scripts somehow but would 
rather avoid that since it slows down the cycle and would make scripts 
non-stock.

Ok, can you try to rmmod forcedeth before hibernation, then insmod it
after resume?
