Description of problem: When doing suspend-to-ram on a Dell Latitude D505, it does not survive resume. On startup it flashes caps lock and scroll lock, turns on the backlight on the black screen, but otherwise does not respond at all. It does not respond on pings. Hibernate works, though. This is a regression from Fedora Core 6, where suspend worked like a charm! Version-Release number of selected component (if applicable): Fedora 7 test4, kernel version 2.6.21-1.3116fc7 How reproducible: Always. Steps to Reproduce: 1. Boot up Fedora 7 2. Close the lid, or choose suspend 3. Open the lid, or press power button Actual results: Non-functional system, flashing caps lock and scroll lock Expected results: Working system
have a look at http://people.freedesktop.org/~hughsient/quirk/ and see if any of that helps :-)
re-assigning to hal-info (adding quirks helped for my d620, prolly will for you too).
Okay, I've really spent some time trying to get this to work now. I have suspend working, under certain conditions: First, I have to unload the module 'uhci_hcd'. I've created the file /etc/pm/config.d/unload_modules, with this content: SUSPEND_MODULES="uhci_hcd" This gave me the ability to resume from suspend without a kernel panic (the kernel panic is what causes the Caps-lock LED to flash). After that, everything worked except the display. It stayed solidly off with not even the backlight turning on. I then tried, to the best of my ability, any combination of the suggested video quirks from http://people.freedesktop.org/~hughsient/quirk/ No luck. This behaviour seems similar to what is reported in bug 240964. My video card is a Intel Corporation 82852/855GM Integrated Graphics Device (rev 02). I was using the i810 driver, version xorg-x11-drv-i810-2.0.0-3.fc7. So I tried to switch to the intel driver. This was not a painless process, and it still doesn't work, I can only get it to work on my external monitor, but with that driver, and the module uhci_hcd unloaded, SUSPEND/RESUME WORKS! Now, why do I need to unload uhci_hcd, and how do I debug it? Should I report it as a separate issue? Why can I not get video to resume, using the i810 driver? How do I debug it? Should I report it as a separate issue?
I'm unsure which update fixed it, but now suspend/resume works with the i810 driver too, provided I blacklist uhci_hcd and give the quirk power_management.quirk.vbe_post. During the weekend I will generate and send the patch for the Dell Latitude D505.
Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again.
It seems to me to be a duplicate of 282871. (The other bug was filled more recently, but I just closed it). Re-open if you think it is not true. *** This bug has been marked as a duplicate of 282871 ***
