The error occurs when the cb_alloc tries to assign a PCI bus and resurces to the card. My computer is: Toshiba Tecra 8200. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Insert Adaptec SlimSCSI 1480B card 2. See the kernel's dmesg output. 3. 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 Additional info: 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. -- Dave Hinds
I tried 2.4.20_rc1 kernel, and it works fine with aic7xxx driver. Thanks Dave !
