by this commit, we noticed persistent error while loading disks:

[   50.323405][  T314]
LKP: ttyS0: 286: can't load the [  183.977924][  T314] LKP: stdout: 286: can't load the disk /dev/disk/by-id/ata-INTEL_SSDSC2BB800G4_PHWL4171000P800RGN-part2, skip testing...

which doesn't show on parent 12c8c13635385a which bot chose as base for this
commit:

* 21ad75d75a0d6b (linux-review/Philipp-Stanner/PCI-Check-BAR-index-for-validity/20250304-224213) PCI: Check BAR index for validity
*   12c8c13635385a Merge branch 'pci/misc'

if need a different base, please let us know. Thanks!
