Hello! I use PCIe device xr17v358 to make UARTs on my motherboard (https://www.exar.com/product/interface/uarts/pcie-uarts/xr17v358). But UARTs work correctly only if I boot Linux kernel with "pci=nomsi" parameter.
I can always see and operate with PCIe configuration space correctly, but normally (without "pci=nomsi" parameter) xr17v358 driver never enters its interrupt routine, that is used for transmit/receive characters. Can this somehow be a BIOS issue or it is more likely a xr17v358 driver issue?
