ICH7 and TI PCIxx12 Cardbus Controller

Sat Jan 6 13:49:18 EST 2007

Dear list.

I've already post a similar message 2 weeks ago, but message subject was 
only about "Sierra Wireless Card", and the ones that may be concerned by 
the bug may simply have discarded the message.

THIS MESSAGE IS NOT ABOUT SUPPORT REQUEST FOR USING A SPECIFIC CARD. I 
CAN USE THE PCMCIA CARD ON ANOTHER LAPTOP WITH EXACTLY THE SAME 
CONFIGURATION, BUT WITH DIFFERENT CONTROLER. THIS IS NOT A CONFIGURATION 
PROBLEM !!

The problem has very similar symptoms to the Yenta TI/ICH6 problem
(bugzilla.kernel.org : 2944). I have ICH7 based laptop (Acer Aspire
9814WKMi).

I've checked that the bug #2944 "parent subordinate# fixup" patch
provided was already present in my kernel (2.6.19). It does not work,
even with this patch.

I've tried to track bug into the 2.6.19 kernel, without success. Here is
the scenario :
    - serial_cs cannot get good parameters for serial port. port, ttyS1,
is then badly configured. UART is not detected.
    - in simple_config, line 479, pcmcia_get_configuration_info retur
successfull, but (config.Attributes & CONF_VALID_CLIENT) is False !!
    - this mean that for my device
(pcmcia_device->function_config->state & CONFIG_LOCKED) is true. I
tested it.
    - I could not figure why. I disabled this check, so that
pccard_get_configuration_info execution reach bottom of the function,
thinking that CONFIG_LOCKED is "accidental".
    - It didn't changed anything... I stopped tracking bug here. I'm
sorry, but I do not well understand PCMCIA/PCI tricks, and code lacks of
comments :-)

Then I tried kernel 2.6.20-rc1-mm1, which embed last git pcmcia code. It
seems better:
    - Setserial /dev/ttyS1 tells me serial port IRQ is #21, as in
windows XP, instead of 3, totaly wrong
    - UART is not detected.
    - (pcmcia_device->function_config->state & CONFIG_LOCKED) is still 
true...

Here is interesting parts of my dmesg:

By the way, the all-in-one card reader does not work. dmesg tells many
IO errors when trying to access the inserted SD card. I think both
problems have same origin : IO mapping.

Sorry for the long post.

I'm waiting your instructions to definitively track and kill those bugs.
