However, the b44 module is then unable to determine its MAC address correctly, and ipw2100 claims that it can't find a device. yenta_socket gives Yenta : Enabling burst memory read transactions Yenta: Using CSCINT to route CSC interrupts to PCI Yenta: Routing CardBus interrupts to PCI Yenta TI: socket 0000:02:06.0, mfunc 0x00001000, devctl 0x66 Yenta TI: socket 0000:02:06.0 probing PCI interrupt failed, trying to fix Yenta TI: socket 0000:02:06.0 falling back to parallel PCI interrupts Yenta TI: socket 0000:02:06.0 no PCI interrupts. Fish. Please report. The only output from the AGP driver is: agpgart: Detected an Intel 855PM Chipset. agpgart: AGP aperture is 32M @ 0xe2000000 If I have all of these drivers loaded at suspend, resume fails. Without intel-agp, I can suspend and resume happily (well, X won't start after resume, but that's potentially an entirely separate issue) -- Matthew Garrett | mjg59-1xO5oi07KQx4cg9Nei1l7Q@public.gmane.org ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
