Judging from your ehci workaround I think your suspend/resume issue is not
i915 related. You mention though somewhere that you also experience memory
corruption issues after hibernat (assuming I've read the comments
correctly). We are aware of memory corruptions issues due to i915.ko when
hibernating, unfortunately no one has yet root-caused this. See e.g.
https://bugs.freedesktop.org/show_bug.cgi?id=35648

thx, for the response.
unfortunately this memory corruption appears not in S4, but after
filed S3.
Looks like some part entered S3 state and never come back, even after
poweroff. I think it, because in some cases power-led blinking after
poweroff - which indicate S3 state. Are there any thing to check to
see what is misconfigured?
I agree, that i915 is not the reason of this problem, but i915 make it
impossible to get oops trace! Any chance to get it work?

As already mentioned by Jesse in the bugzilla, just blacklist it. We don't
really support nomodeset (because for things like suspend/resume it's
actually impossible to properly support).

I did response on the bugzilla - blacklisting the module do not help. i
get just black screen, no oops trace. Are there any way to get trace
with modeset?

Well, if you've checked that none of the i915, drm and intel-agp
modules are loaded with lsmod there really shouldn't be any difference
cause by modeset or nomodeset. I.e. if that's the case, your black
screen is cause by a suspend/resume failure caused by another driver.

ufff... again not understood.
>>> i know this issue isn't fault of intel graphic <<<
with my older intel laptop i was able to get oops trace in such case.
With new intel hardware i get blank screen with cursor in left top corner.
>>> Instead of cursor i expect oops trace! <<<
Is it possible? If not please say so. If yes, then is is a bug.

Well, I'm not a suspend/resume expert, so I don't quite know whether you
should get an oops. Also the bios might do funky stuff or the
suspend/resume ordering changed meanwhile. So I have no idea :(

ok, thx.
then i will need to look for other way to get some debug info.
I have this port on my laptop:
https://bugzilla.kernel.org/attachment.cgi?id=72351
do you accidental know some thing about it?
