I can provide additional information on > request. I can also create an entry in bugzilla if needed. Please put an entry into bugzilla and also add a backtrace with CONFIG_FRAME_POINTER enabled. Your current backtrace looks extremly noisy Anyways it looks like a ioremap() with zero or negative argument somewhere triggered by the ACPI processor module load. Right now I'm not quite sure who calls the ioremap though. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
