The wireless PC card is device 0000:00:0e.0. And replacing ioremap() with ioremap_nocache() did
not help either.
This is the PCI entry for the host bridge:
00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03)
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: 64
Region 0: Memory at ec000000 (32-bit, prefetchable) [size=64M]
Capabilities: [a0] AGP version 1.0
Status: RQ=32 Iso- ArqSz=0 Cal=0 SBA+ ITACoh- GART64- HTrans- 64bit- FW- AGP3-
Rate=x1,x2
Command: RQ=1 ArqSz=0 Cal=0 SBA+ AGP+ GART64- 64bit- FW- Rate=x2
One other thing I should mention is that this card works fine in an old P120/Zappa motherboard
machine running Linux 2.4.34.
Cheers,
Chris
