Description of problem:
When I insert Adaptec 1480B PCMCIA CardBus card I got the attached error
messsage in dmesg.
The error occurs when the cb_alloc tries to assign a PCI bus and resurces to the
My computer is: Toshiba Tecra 8200.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Insert Adaptec SlimSCSI 1480B card
2. See the kernel's dmesg output.
Actual Results: cs: cb_alloc(bus 5): vendor 0x9004, device 0x6075
PCI: Failed to allocate resource 0(e000-dfff) for 05:00.0
PCI: Failed to allocate resource 1(f8000000-f7dfffff) for 05:00.0
PCI: Failed to allocate resource 6(f8000000-f7dfffff) for 05:00.0
PCI: Enabling device 05:00.0 (0000 -> 0003)
SCSI subsystem driver Revision: 1.00
PCI: Setting latency timer of device 05:00.0 to 64
aic7xxx: PCI Device 5:0:0 failed memory mapped test
ahc_pci:5:0:0: No SCB space found
The situation was the same with RedHat 7.3 too.
If I disable the kernel pcmcia driver in a custom kernel, and install
pcmcia-cs from pcmcia-cs.sf.net, the apa1480_cs driver can initialize the card
with the PnP resource checking option.
I tried it with RedHat 7.3.
This is a kernel PCI subsystem bug having to do with resource selection for
devices behind PCI-to-PCI bridges. I believe that it is fixed in the current
(2.4.20-pre and 2.5.45) trees. There is no work-around for older kernels.

I tried 2.4.20_rc1 kernel, and it works fine with aic7xxx driver.
Thanks Dave !
