Hi,
Somewhere between kernel v3.15 and v3.18 several PCI ID refs went missing.
By accident, I presume. Kernel v3.14 is fine.
This might just be the tip of iceberg, so to speak, as more PCI ID refs
are probably missing.
In v3.14:
- "0000:03:00.0" was shown as "pata_pdc2027x" (PCI ID: 105a:4d68)
- "0000:00:1f.2" was shown as "ahci" (PCI ID: 8086:1c02)
- "0000:06:00.0" was shown as "ahci" (PCI ID: 1b21:0612)
