The logged device ID 06:00.0 is the HPE SATA controller. The errors go away after a reboot until the problem occurs again after a few hours. In most cases, the server even reports a hardware fault and the storage fan spins up to 100 %. The problem did _not_ occur in Ubuntu 20.04, the last 20.04 kernel I ran on this server was 5.13.0.39.44~20.04.24. Setting the intel_iommu=off kernel boot parameter seems to work around the problem.
