The file system errors created by a panic (especially an NMI panic) could easily be more problematic than a failed PCIe data transfer. Evan a read that returned ~0u - which can be checked for. Panicking a system that is converting TDM telephony to RTP for the 911 emergency service because a PCIe cable/riser connecting one of the TDM board has become loose doesn't seem ideal. (Or because the TDM board's fpga has decided it isn't going to respond to any accesses until the BARs are setup again...) The system can carry on with some TDM connections disabled - but that is ok because they are all duplicated in case a cable gets cuit. (Yes - that is a live system...)
