Hi guys,
while trying to fix a problem with a Bluetooth PCMCIA card I faced the problem that my Cardbus controller don't give out any interrupts. I tried it with 2.6.5 and this is my PCMCIA bridge:
0000:02:0e.0 CardBus bridge: Texas Instruments PCI1410 PC card Cardbus Controller (rev 01) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 168, Cache Line Size: 0x20 (128 bytes) Interrupt: pin A routed to IRQ 18 Region 0: Memory at 20000000 (32-bit, non-prefetchable) Bus: primary=02, secondary=04, subordinate=07, sec-latency=176 Memory window 0: 20400000-207ff000 (prefetchable) Memory window 1: 20800000-20bff000 I/O window 0: 00004000-000040ff I/O window 1: 00004400-000044ff BridgeCtl: Parity- SERR- ISA- VGA- MAbort- >Reset+ 16bInt+ PostWrite+ 16-bit legacy interface ports at 0001
And this is how /proc/interrupts look like:
CPU0 0: 7241752 IO-APIC-edge timer 1: 10923 IO-APIC-edge i8042 2: 0 XT-PIC cascade 8: 4 IO-APIC-edge rtc 12: 94 IO-APIC-edge i8042 14: 134100 IO-APIC-edge ide0 15: 1 IO-APIC-edge ide1 18: 0 IO-APIC-level yenta 19: 120010 IO-APIC-level uhci_hcd 20: 0 IO-APIC-level ohci_hcd 21: 231886 IO-APIC-level ohci1394, ohci_hcd, eth0 22: 297 IO-APIC-level acpi, ehci_hcd 23: 57 IO-APIC-level aic7xxx, uhci_hcd NMI: 0 LOC: 7241898 ERR: 0 MIS: 0
The count for interrupt 18 is still zero every time, but on my Sony C1VE laptop the PCMCIA cards get their interrupts.
Regards
Marcel
