--- Comment #9 from Austin Lund <austin.lund at gmail.com> --- Created attachment 80547 --> https://bugs.freedesktop.org/attachment.cgi?id=80547&action=edit pci_restore_config_dword debugging when resuming with dGPU off at suspend It is log output like this that worries my about the 0xff reads from the pci config space. I set this in dynamic_debug: drivers/pci/pci.c:964 [pci]pci_restore_config_dword =p "restoring config space at offset %#x (was %#x, writing %#x)\012" Then it gives this 0xff writing to the pci address space on restore when using the integrated gpu. Surely this cannot help. My guess is that the hardware should be removed from the kernel when the power is turned off. But that's just a hunch. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
