Summary0017132: NI PXI Serial cards are identified as broken devices, Serial driver unable to bind with it.
DescriptionThe native serial driver is unable to bind with NI PXI Serial hardware as there is a missing patch that meant to be fixing this fatal issue. Request to apply this patch to make PXI Serial hardware non-fatal again. This patch was already in the latest kernel and back-ported to kernel 4.14, 4.19 and 4.20 but not 4.18, this is why the issue is seen in CentOS 8.
Steps To Reproduce1. Install any PXI Serial RS-232 hardware into system.
2. Boot into CentOS 8, observe that the serial devices is not enumerated properly in the system, ttyS is missing.
Additional InformationObserve that the serial interfaces are shown when do "lspci -k" but no serial ports are enumerated and associated kernel module/driver.
