hope it is sufficiently complete
for you to make progress in debugging why my machine is unhappy.
Please don't hesitate to ask, if you think I can provide other data
and/or run other tests.

Just wondering if any of you had any other ideas of what I could try
to help debug this problem?
Thanks,

As I said earlier in this thread, echo'ing "devices" into "pm_test"
does not result in a crash; but doing so for "platform" does.

I am back and have physical access to the machine now.
I re-ran the test just to be sure, and I can confirm that "platform"
does in fact result in a crash.
Furthermore, I ran the test that Rui asked for. I suspended, resumed,
and upon crashing power-cycled the machine ASAP. "dmesg" suggests that
"platform" does in fact appear to cause a crash (at least, I can't
reach the machine anymore, after having suspended).
I am still on the road and have to do this remotely, and I cannot get
hold of my helper right now. I'll try again later tonight or maybe the
next day(s) and will get back to you w
I tried removing snd_hda_intel, but it didn't make any difference.
I then followed your instructions to turn on tracing, but I am more
puzzled than I was before. The crash reliably happens, every time I
suspend/resume without first having tracing turned on. But as soon as

Sorry for the delay. Remotely debugging kernels over a shared and
flaky 1MBps terrestrial wireless connection is quite a new experience
to me.
In any case, I was able to collect all the data that you asked for. I

Please note the crash in "dmesg" right after booting. This looks relevant:

My Dell M4400 has been pretty well-supported by Linux a couple of
years now, but recent 3.16-rcX cause hard crashes when resuming from
Suspend-to-RAM.
This is tricky to debug, as device drivers are not yet restored by the
time that the crash happens. So, I can't use Page-UP to scroll the
screen an
I have done some more testing, and it now looks as if this was actually
a hardware fault. Reseating the PCI-E card made the problem go away
(knock on wood). I am a little puzzled that it is possible for the card
to show up on the PCI bus, and for the driver to be able to detect
whether a disk i

I just wanted to remind you that you need to be careful about dumping
