Without > intel-agp, I can suspend and resume happily (well, X won't start after > resume, but that's potentially an entirely separate issue) I've tracked this down some further. If I comment out these lines in intel_845_configure: /* agpm */ pci_read_config_byte(agp_bridge->dev, INTEL_I845_AGPM, &temp2); pci_write_config_byte(agp_bridge->dev, INTEL_I845_AGPM, temp2 | (1 << 1)); then I can load intel-agp, suspend and resume and still get correct interrupts. If I leave then uncommented, then attempting to load yenta-socket after a suspend/resume with intel-agp loaded results in the "no PCI interrupts. Fish" error. This is an i855PM device using nvidia graphics. -- Matthew Garrett | mjg59@srcf.ucam.org
