Description Jens Knutson 2007-05-06 17:10:02 EDT
Description of problem:
When trying to restore from suspend, my Dell e1505 / MM061 (the latter code is
what hal reports as "system.hardware.product"), I get a plain black screen. 
When in this screen, the keyboard is non-responsive - Ctrl Alt Del does nothing,
and I am forced to hold down the pwr button for 5 secs to force shutdown.

Version-Release number of selected component (if applicable):
(I filed this bug against the X driver as a best guess.)

How reproducible:

Steps to Reproduce:
1. Suspend laptop
2. Restore laptop
3. Stare angrily at empty black screen, be forced to perform hard shutdown

Additional info:
This is a regression from FC6, where it worked perfectly.
Comment 1 Oleg Drokin 2007-05-14 15:18:34 EDT
I'd probably join this report (amongst quite a few similar ones).
suspend2RAM worked quite well in FC6, but after I upgraded to FC7beta4, I got
black screen & dead system on resume.
Now after updating my kernel to 2.6.21-1.3142.fc7 today, I cannot even suspend
anymore, machine freezes after printing Suspending Console(s).
Booting into 2.6.20-1.2944.fc6 makes suspend usable again, of course.
Comment 2 Oleg Drokin 2007-05-14 15:21:46 EDT
Hm, component in this bug is obviously wrong, because the problem is definitely
in kernel. and I clearly can reproduce without any sort of X environment
running, unfortunatelly I am not allowed to change it.
(also I have Dell Latitude D620 Core2Duo system, which I forgot to say earlier)
Comment 3 Jens Knutson 2007-05-14 16:53:52 EDT
Thanks for the tip, Oleg!  I've changed the bug accordingly.

Also, as of 2.6.21-1.3149.fc7, I get the same problem as Oleg.  I can't even
suspend, much less restore - it gets stuck at "Suspending Console(s)", just as
he described.

Can you try the steps at http://people.freedesktop.org/~hughsient/quirk/ and see
if you need to blaklist a module. Thanks!
Comment 5 Jens Knutson 2007-07-19 02:15:54 EDT

ok, I'm just a little excited.  *cough*

Using the git hal-info vid quirks file for my laptop, everything works 100% with

Everything.  No hacks.  No blacklisting.  Nothing.  It just WORKS.... like in
FC6. ;-)

Closing, RAWHIDE
