The an driver fails to recognize the Aironet mini PCI wireless 
card.  I modified /usr/src/sys/dev/pci/if_an_pci.c to include

        { PCI_VENDOR_AIRONET,           0xa504},

and I also added the folling in my kernel config:

   an*     at pci? dev ? function ?

but all I get now is

an0 at pci2 dev 2 function 0: Aironet Wireless Communications product 0xa504
pci_io_find: expected type i/o, found mem
an0: unable to map registers

I also have the following pcictl data from the card:

I also tried adding the folling line to 

  #define       PCI_PRODUCT_AIRONET_MPI350      0xA504 

and added the following to pcidevs_data.h:

            "Cisco/Aironet Wireless Communications",
            "Cisco/Aironet MPI350 mini PCI Wireless LAN Adapter",

and added the following to if_an_pci.c:


thinking that might be the more proper way to do it...but the 
result was the same.

I also tried changing 0x18 to 0x10 in if_an_pci.c 

     #define AN_PCI_IOBA             0x18    /* i/o base */

but that panic's my kernel and the laptop doesn't boot.

I don't know what else to try but I would be happy to test changes
for anyone.

Sam Tannous
configure an support and change the if_an_pci.c code to 
recognize the product code in a Thinkpad T30 and reboot.
None that I know of....

 ...some more testing.....

 In usr/src/sys/dev/pci/if_an_pci.c, I tried switching 
 kernel panic:

 an0: interrupting at irq 11
 an0: failed to load config data
 an0: failed to attach controller
 extent 'iomem' (0x0 - 0xffffffff), flags = 0x3
    0x0 - 0x9eff
    0xa0000 - 0xbffff
    0xc0000 - 0xc7fff
 <snipped 7 line>
    0xffb00000 - 0xffbfffff
 extent_free: start 0xd0400000, end 0xd040003f
 panic: extent_free: region not found
 Stopped in pid 0 (swapper) at cpu_Debugger+0x4:   leave

 I also tried an additional change (leaving PCI_MAPREG_TYPE_MEM
 there) and changed 

 #define AN_PCI_PLX_IOBA         0x14  /* i/o base for PLX chip */
 #define AN_PCI_IOBA             0x14    /* i/o base */

 (The difference was changing AN_PCI_IOBA from 0x18 to 0x14).
 But I got the same kernel panic (as shown above).

 The odd thing is that the T30 also comes with a TI mini-PCI
 card which works fine with the wi driver.  My T30 also works
 fine with FreeBSD 4.7 and 5.0 if I simply enable the an driver.

 Let me know if you need any further testing or troubleshooting....
