Hi, I got a bug report about some systems generating an NMI and subsequently crashing bisected down to 80696f991424d. Apparently these systems do not react well to __pciehp_enable_slot while no card is present. Restoring the check to __pciehp_enable_slot() removed in 80696f991424d makes the current kernels work. What is to be done? Do you want a special case for the affected systems based on DMI, or should I revert 80696f991424d? Regards Oliver
