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) # snippet from /proc/interrupts CPU0 CPU1 0: 15 0 IO-APIC-edge timer 1: 31 0 IO-APIC-edge i8042 4: 39043 0 IO-APIC-edge serial 5: 1 0 IO-APIC-edge parport0 8: 111 0 IO-APIC-edge rtc0 9: 3 0 IO-APIC-fasteoi acpi 12: 144 0 IO-APIC-edge i8042 16: 99 0 IO-APIC 16-fasteoi ehci_hcd:usb1 18: 5173 0 IO-APIC 18-fasteoi 0000:03:00.0 19: 2871417 0 IO-APIC 19-fasteoi eth0 23: 33 0 IO-APIC 23-fasteoi ehci_hcd:usb4 24: 759 0 PCI-MSI-edge 0000:00:1f.2 25: 16582 0 PCI-MSI-edge 0000:06:00.0 26: 29172 0 PCI-MSI-edge eth1 27: 502 0 PCI-MSI-edge snd_hda_intel 28: 0 0 PCI-MSI-edge xhci_hcd 29: 0 0 PCI-MSI-edge xhci_hcd 30: 0 0 PCI-MSI-edge xhci_hcd 31: 17 0 PCI-MSI-edge i915 # snippet from lspci 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family SATA AHCI Controller (rev 05) (prog-if 01 [AHCI 1.0]) Subsystem: Micro-Star International Co., Ltd.
