Same failure with 2.6.34 (Linus tree head as of five minutes ago), I'm afraid.

Not a laptop: I'm suspending to cut my electricity bill (by nearly 30% at last
count, ouch).
This is a 2.67GHz Intel Core i7 920 (stepping 4) on an Asus P6T motherboard.

If there was some way to get info out of the system while the freezer is
engaged I'd generate some and give you the freeze point, but unfortunately the
network card appears to be one of the frozen entities, so netconsole and
presumably kgdb-over-Ethernet are unhelpful. (None of my machines have serial
ports, only serial-over-USB, so serial-kgdb isn't useful in this situation
either.)

dmesg of suspend-crashing kernel
Here's the dmesg. Are you sure you want an X log as well? This crash happens if
you suspend from the textual login prompt without ever going near X, so it
seems as if it would be superfluous to me.

Ok works here, please test without tuxonice, tuxonice is know to be problematic
and it's out of tree so i won't have time to fix it.

Er, how do I suspend without tuxonice? I've never used the in-tree swsusp
successfully (last time I tried I didn't just get a crash but massive
filesystem corruption, so I sort of haven't dared: reporting it would have
meant reproducing it, and I didn't want to touch it with a bargepole after
*that*).
Ideal would be a way to kick off the freezer and then just unfreeze without
suspending: that'd be pretty much risk-free...

It's kind of strange given that quite a few people use it daily, including
everyone using hibernation in the default openSUSE setup.
Anyway,

# echo core > /sys/power/pm_test
# echo disk > /sys/power/state
should do the trick.

Oh, *thank* you, that's very useful indeed.
That lets me eliminate virtually everything from consideration, because it
works with ToI off (but patched in) and fails with it on! Thus the problem is
either a ToI bug (and likely a bug in not very much ToI code; most of the ToI
code relates to block writeout, not freezing), or a bug in the core kernel
tickled by ToI.
(btw, I'm willing to believe my fs damage when last I tried the core suspension
code was my fat-fingering, not the code itself. It plainly wasn't the freezer,
whatever it was, as ToI uses that too, and that worked.)

I think the issue is that Tuxonice assume somethings about graphic driver which
is wrong with kms. Somethings about memory, ttm is messing with memory and
tuxonice maybe miss that and don't properly save our memory.
