PCIe Bus Error

PostWed Apr 10, 2019 4:55 pm

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.
