Assigned interrupts ... what's correct ?

Show all headers | View raw

Hi,

I have tried to find out what IRQ has been assigned to the devices of my 
SuSE/Intel machine ... and I got different infos.

I'm really confused and here is what I did:

lspci -vvv

02:00.0 Ethernet controller: Atheros Communications L2 Fast Ethernet 
(rev a0)
         Subsystem: ASUSTeK Computer Inc. Device 8233
         Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- 
ParErr- Stepping- SERR- FastB2B- DisINTx+
         Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- 
<TAbort- <MAbort- >SERR- <PERR- INTx-
         Latency: 0, Cache Line Size: 16 bytes
         Interrupt: pin A routed to IRQ 43  <=======

--------------------------------------------------------

lspci -vvv -H1

02:00.0 Ethernet controller: Atheros Communications L2 Fast Ethernet 
(rev a0)
         Subsystem: ASUSTeK Computer Inc. Device 8233
         Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- 
ParErr- Stepping- SERR- FastB2B- DisINTx+
         Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- 
<TAbort- <MAbort- >SERR- <PERR- INTx-
         Latency: 0, Cache Line Size: 16 bytes
         Interrupt: pin A routed to IRQ 10 <=======

---------------------------------------------------------

Any comments ?
