 |
|
Hello,
I just updated my laptop with KDE 4.6.3, baselayout 2, fglrx 11.6 and now when I resume from suspend (sleep) the screen is black and I must to force reboot.
What can I do to debug this issue?
Thank you very much for any kind of help!
Cheers. |

| What kernel version are you using? Does it work in an untainted kernel? |

Hi, thanks for the reply.
I'm using gentoo 2.6.38-r6. It worked very well with kde 4.4.5 and previous kernels. |

Please let me know what kind of information is needed in order to solve this issue.
Thank you very much for any kind of help. |

Yes, using pm-suspend without any loaded module (=untainted kernel?), suspend works perfectly.
Here my actual modules:

In order to allow the suspend, I need to remove xhci_hcd, using /etc/pm/config.d/suspend_xhci_hcd
| Code: | | SUSPEND_MODULES="xhci_hcd" |
Just for precaution I do the same for wl on my /etc/pm/config.d/suspend_wl
| Code: | | SUSPEND_MODULES="wl" |
Thank you very much for any kind of help. |

Running without any loaded modules will give you an untainted kernel, but does not provide the answer we need. We need to see if it works when you load everything except the tainted module(s). That will then tell us whether the bug lies in the tainted module or in some other component. If the bug is in the tainted module, then you need to seek help from the vendor who provided that module to you. If the bug is reproducible in an untainted kernel, then upstream may be able to help you. |

Ok, found.
In this case, the evil module is r8169, suspending with the pm-utils, solves the problem.
Thank you very much for your support. |

hi there!
i had problems with r8169 and suspend too.
actually, i just want to add, that if the module is loaded before suspend or compiled into kernel, machine wakes up but very slowly (~1min).
when r8169 is as a module and unloaded or it's support is switched off from kernel - machine wakes up normally ) |

| Does it helps, if you press Ctrl+Alt+F12 and after that Ctrl+Alt+F7 ? |
