So, here's something funny. The suspend/resume failures started
happening for me on September 20, almost exactly 3 years after I'd
gotten the machine; and was reproducible with older kernels and OSes
that had previously worked fine. I had joked that maybe the BIOS had a
time bomb in it, or just
I did just have a suspend/resume failure, but it was the first one after
many repeated test suspend/resume cycles and it was also the first time
I was transporting the laptop so could have been a physical connection
coming loose anyway (I thought it had suspended successfully before I
put it in
@Steve, as per discussion on IRC, you mentioned that this bug may be due
to just buggy H/W. Do you want to keep this bug open?

I've added a considerable amount of debug into the suspend path in the
kernel.
1. Edit /etc/default/grub and set:
GRUB_CMDLINE_LINUX_DEFAULT=loglevel=7 no_console_suspend
2. Download and install the kernel .debs from:
http://kernel.ubuntu.com/~cking/lp-1228406/v1/
3. Reboot
4. Switch to
I wonder if the issue is because you have a different wireless card and
this is causing the firmware some issues when coming up from a clean
start on resume.

It's not a matter of anything happening on resume, fwiw; it doesn't suspend

Steve Langasek, as per http://download.lenovo.com/express/ddfm.html an
update is available for your BIOS (6QET70WW). If you update to this
following https://help.ubuntu.com/community/BiosUpdate , does it change
anything?
If not, could you please both specify what happened, and provide the output
No. I have an aftermarket wlan card in this system that prevents using
the stock bios from Lenovo, and Tue tools for unpacking bios images for
modification appear to have bit rotted.

It's been another 10 days since I last posted, and I still haven't
encountered this bug again. I have no idea if it was the new kernel
version or the BIOS that fixed it - I updated them both within a
couple of days of eachother, so I am running the latest BIOS that
Christopher linked to. Of course

@Steve, perhaps you can confirm if 3.11.1-031101 solves the problem. If
so, I can start to track down any potential fixes we're missing.

Ignore that comment, this bit is already forced on suspend nowadays.

I've had this issue ever since I first put Ubuntu (13.04) on my laptop
in May. I updated my kernel to 3.11.1-031101-generic 2-3 weeks ago and
it hasn't happened since. I don't know if it's just luck, or if it's
actually been fixed (there have been other times where it hadn't
happened in a while,
I should add that I have the same laptop as Steve (Thinkpad X201).

That's a great question. Last night, my results
Steve, just to factor out some of the pm-utils complexity can you boot
into 3.11.0-4 and switch to a console and try:

Failing that, do you have any earlier kernels to try this out on to see
if they work or fail?

So for the first time today I had occasion to try suspending my laptop
when I wasn't in a hurry to immediately shove it in my bag, and observed
the following:
- on lid close, the suspend light blinks for a little while (as usual)
- then the machine beeps (as usual)
- the suspend light then
This behavior (fans spinning on suspend, power off after a minute) is
consistently reproducible at least back to 3.11.0-4. I definitely did
not experience this problem while 3.11.0-4 was current. So it looks
like something else may have changed to cause this bug.
I am able to reproduce the
Do you happen to recall the last 3.11 kernel that did not exhibit this

Also, another helpful test would be to see if this happens with 3.12-rc2, which
can be downloaded from:

I don't remember seeing this with 3.11.0-6, but that's not worth much;
it may have just not become an issue for me that was worth reporting
until I was traveling (and therefore suspending/resuming more often) and
