I've narrowed down the problem for devices in HBA mode; if device is in RAID mode (despite if it's effectively using some raid level or has only 1 disk), it does not reproduce the issue. I'll attach files with outputs from HP RAID utility (accessed in BIOS) for both cases. I continue the investigation.
