From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.1) Gecko/20020827 Description of problem: My hardware is only supported by pcmcia-cs version 3.2.3, because of a bug in any version up to 3.2.2. Could you please update your very old version 3.1.31 dated from 2002-01-02? Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Insert 3com 3c589 2. Recognize that the card is seen as memory (instead of NIC) 3. Update to pcmcia-cs 3.2.3 4. See its working now. Actual Results: Card is recognized as memory: PCI: Assigned IRQ 9 for device 00:0d.0 Cirrus PD6729 rev 00 PCI-to-PCMCIA at slot 00:0d, port 0x3e0 host opts [0]: [ring] [1/3/2] [1/9/2] host opts [1]: [ring] [1/3/2] [1/9/2] ISA irqs (default) = 3,4,7,9,10,11,12 polling interval = 1000 ms cs: memory probe 0x0d0000-0x0dffff: excluding 0xd0000-0xdffff cs: memory probe 0x0c0000-0x0cffff: excluding 0xc0000-0xcffff memory_cs: mem0: anonymous: unknown size Expected Results: Card should be recognized as a network pcmcia 3c589.

we don't ship any of the pcmcia-cs kernel bits but use the 2.4 kernel bits instead, and unfortionatly the bug you reference has no real useful information ;(
Taken from PCMCIA-HOWTO: In the standalone pcmcia-cs drivers, the i82365 module supports both ISA-to-PCMCIA, PCI-to-PCMCIA, and PCI-to-CardBus bridges. The CardBus socket driver in the 2.4 tree is the yenta_socket driver. It is selected by the CONFIG_CARDBUS option. In your PCMCIA startup options, this driver should be specified in place of the i82365 driver. The kernel version of the i82365 driver, selected by CONFIG_I82365, only supports ISA-to-PCMCIA bridges. PCI-to-PCMCIA bridges that are not CardBus capable, like the Cirrus PD6729, are not supported at all by the kernel PCMCIA drivers. My card controller is a PD6729. This means, it is not supported by RHAT 8.0 because you are using the kernel drivers. So I ask you to deliver the standalone pcmcia-cs drivers. However, because of a bug in pcmcia-cs up to and including 3.2.2 you should use at least 3.2.3. The bug in detail could be seen from the patch attached. The author writes in its CHANGES: Fixed i82365 driver to do a better job of initializing PCI bridges on 2.4.* kernels.
Created attachment 84445 [details] patch for pcmcia-cs fixing the initialisation problem for pd6729
that howto is not quite correct. Linux 2.4 does support PCI->PCMCIA bridges. However not all of them right now; mostly because of lack of hardware availability. Looking at the datasheet briefly, it appears to not be too hard to add pd6729 support into that driver assuming you are willing to test.
Yes! I would love to do anything to elminate the bug. I could test your driver and also do some minor modifications (if you tell me what). I program C since years, so trying out various #ifdef's is no problem. Feel free to tell me what to do!
Just to make one last thing clear. The PD6729 _is_ supported by the standalone pcmcia-cs drivers. So it might help looking at "i82365.c" from pcmcia-cs, because this is working!
Have you made any progress yet? Is there anything I can test or help? Please let me know.
