PCIe Bus Error

Hello, when I'm trying to capture stills using samples from SDK (and own application derived from them) via DeckLink Mini Recorder, I'm experiencing high CPU load by systemd-journald which I've traced to these messages in syslog:

(repeating every few milliseconds)

Has anyone encountered this behaviour? I've found few reports (with different HW) that suggest I should swap PCIe slot or update BIOS. Or maybe kernel is not supported? Thanks in advance.
