| Summary | 0017132: NI PXI Serial cards are identified as broken devices, Serial driver unable to bind with it. | ||||
| Description | The native serial driver is unable to bind with NI PXI Serial hardware as there is a missing patch https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=824d17c57b0abbcb9128fb3f7327fae14761914b 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 Reproduce | 1. 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 Information | Observe that the serial interfaces are shown when do "lspci -k" but no serial ports are enumerated and associated kernel module/driver. | ||||
| Tags | No tags attached. | ||||
