Since v3.7-rc1 I am seeing suspend to RAM fail as well. It was obscured
by a nouveau recursive locking issue on my machine. I reverted the 3.7
DRM merged completely. From there "echo mem > /sys/power/state" works,
but choosing suspend like most mere mortals do results in suspend, but
attempt to resume brings me straight to the BIOS starting anew.

Not sure if it has the same root cause. Since DRM revert did not work
for me I put my money on ACPI (not a lot of money though ;-) ).

I've had this symptom on my laptop (Thinkpad Edge 13, Intel
graphics & CPU; I can get details when I get back home in about 8
hours), but only with 3.7-rc2. It was definitely working in 3.6, and
seems to be OK in 3.7-rc3, although I've only tried two cycles of that
last night.
When I did suspend to disk, I get a blank screen (but clearly with
backlight still on), and a blinking text-mode cursor in the top left.
I left it for half an hour once, and nothing changed, so I'm fairly
sure it was properly hung. I've not seen it return to user space with
errors at all -- just the hang.

I can try to bisect the 3.6 -> 3.7-rc2 failure, if that helps? But
as I said, I've got it working on -rc3, so I may not have the same
problem.

Ugh. I was hoping that we'd get more reports on this, right now
there's not enough information to even make a guess about what's up.
I also note that no actual i915 people were cc'd, despite your
graphics driver suspect. Adding Daniel and Dave (one of the millions)
to the cc since they probably do have lkml but probably don't react
unless something gets pointed out.
Daniel/Dave, do you have any reports of hibernation failing (or VT
switching problems) with i915 after 3.6?
Rafael, do you have logs of the suspicious RCU usage etc reports?

Not at the moment, unfortunately. I'll try to collect some tomorrow,
but I'm leaving for LinuxCon Europre on Sunday morning, so I'm a bit
time constrained now. :-)

Not that I've heard of. We did though rewrite the entire modeset
sequence driving code in i915 for 3.7, removing massive amounts of
hacks and stupid "let's disable/enable things harder" code simply
because the old code couldn't keep track of the hw state well enough.
So I wouldn't be surprised at all if that unearthed a hidden bug
somewhere, but we've also added ridiculous amounts of self-checks. And
thus far they caught all issues due to that rework (and some ancient
bugs on top) when either the i915 driver or the bios did something
nefarious ...
I've rechecked the git log and otherwise there's nothing else which
pops up that would fit VT-switching/hibernate going bad but the
modeset rework.

Can you point me to a range of commits worth checking?

8c3f929b6147e142..57df2ae9df6e335a98969cac is the core rework (plus a
bit related follow-up) without any other merges interfering. Might
oops if you open/close the lid without a suspend/resume cycle (since
that's only fixed later on), should otherwise work.

Well, as it turns out, v3.6.0 doesn't work too with my .config, so never
mind (and thanks for help :-)).
I wonder what's wrong with my .config, though ...

Well, it appears that Tumbleweed has acquired a broken s2disk binary.
Replace it with one built from upstream sources and it magically starts to
work. Grumble.
Sorry for the noise.

Heh. This was the report that so far made me most worried about the
current state of the -rc process, so I'll curse you and be very
relieved at the same time ;)

Ugh. So khubd is blocked in usb_start_wait_urb(), and apparently the
timeout for that block is longer than the freezing timeout.
There's a comment about why khubd needs to be freezable, but I wonder
if that whole thing isn't doing something wrong. Causing the suspend
to fail is definitely always the wrong thing.

Heh. The RCU usage is from the debug printout from sched_show_task(),
so it's "related", but it's a totally independent issue.
It's apparently because we've not done a "rcu_read_lock()" around that
sequence, but I seriously doubt we care. But it's technically a real
bug - even if the fix might be to just not print out the parent pid
(or to just ignore the bug and turn the rcu dereference into an
ACCESS_ONCE() or something.
Ingo, Peter, any comments about that sched/core.c:4497 RCU usage?

khubs has been a potential problem for suspend since the beginning.
The USB spec mandates timeouts of 5 seconds. In addition, khubd does
lots of retries when errors occur (probably way too many) and checks
for freezability only when its to-do list is empty.
Under normal circumstances this isn't a problem. Issues arise when a
non-cooperative device is plugged in shortly before a suspend starts.
I suppose we could scatter a whole bunch of checks at spots throughout
the device-initialization code. This seems awkward but I can't think
of anything better. Does anyone have other suggestions?

Rafael, does the following patch fix that problem?
Thanx, Paul

sched: Mark RCU reader in sched_show_task()

Well, the box I can reproduce that on is not with me now and it's
not readily reproducible anyway, so it may take some time to verify
I'm afraid.
