Environment

SUSE Linux Enterprise Server 12 Service Pack 3 (SLES 12 SP3)
SUSE Linux Enterprise Server 15

Situation

PCIe bus fatal error can occur with NVMe switch card during SLES installation. This can look something like this in the system log:

install kernel: [   26.098321] pcieport 0000:00:01.0: AER: Uncorrected (Fatal) error received: id=0008
install kernel: [   26.098325] pcieport 0000:00:01.0: PCIe Bus Error: severity=Uncorrected (Fatal), type=Transaction Layer, id=0008(Requester ID)

install kernel: [   27.107326] pcieport 0000:00:01.0: AER: Device recovery failed

Resolution

Add kernel parameter: "pci=hpiosize=0K" (where 0 is the number zero) during SLES installation.

A fix for this issue has also been submitted for inclusion in the next SLES 12 and SLES 15 service packs.

Cause

Port 0.x5658 is improperly probed during the early installation as part of hardware detection.
