Compile with CONFIG_PM_VERBOSE (it does mean exactly that).

The last message now was:

e100: 0000:02:08.0: hibernate, may wakeup

Looks like hibernating the e100 driver is unstable.

Can you verify that by trying to hibernate without the e100 driver?

Not really, as I still can't reliable reproduce the issue.  Since I'm
running with suspend loglevel = 8, it's happened only twice (in a row),
with seemingly exact same console output.  Some earlier freezes also
happened in dpm_suspend_start, at least.  However, I can certainly add
e100 to SUSPEND_MODULES under /etc/pm/config.d, and continue running
with that.

That's what I'd do.

That worked out mosty OK (no freeze in quite some hibernation cycles),
but I'm continuing testing it.

Great, please let me know how it works out.

Will do.  On the negative side, this tends to confuse NetworkManager.

On the other hand, I reverted 8fbd962e3, recompiled and replaced the
module, and got the freeze during hibernation.  And that was the bulk of
the changes since 2.6.31...  I'll revert the rest and test again, but
that seems purely cosmetic, so no high hopes.

In addition to that, you can run multiple hibernation/resume cycles in
a tight loop using the RTC wakealarm.

I'll do so, as soon as I find a way to automatically supply the dm-crypt
passphrase... or even better, learn to hibernate to ramdisk from the
initramfs. :)

Well, you don't need to use swap encryption for _testing_. :-)

I use partition encryption, everything except for /boot is encrypted.
Apropos: does s2disk perform encryption with a temporary key even if I
don't supply and RSA key, to protect mlocked application data from being
present in the swap after restore?
