pcmcia irq trouble

pcmcia irq trouble

[Justin Karneges]

Thank you, Matthew and Len, for answering my general questions about 
acpi-devel.

Now, I've discovered a problem, and this may or may not be related to ACPI, 
but I think it is.  If not, I'll be happy to redirect this message to the 
appropriate target.

I'm using the Sony VAIO PCG-VX88 laptop.  Without ACPI, almost none of the 
major peripherals function except for the external PCMCIA slot.  The VX88 has 
an embedded wi-fi which is detected as a secondary PCMCIA slot, but again, 
without ACPI this does not work.  If I recall correctly, the driver would 
report: "RequestIRQ: Resource in use".  I contacted the author of the 
(orinoco) driver, and he claimed this was outside the scope of the driver.  
Indeed, looking at the code it appears that the pcmcia subsystem deals with 
dishing out IRQs, not the actual card drivers.

With kernel 2.4.26-pre5 + today's ACPI patch, everything seems to work, 
including the internal wi-fi, _except_ for the external PCMCIA.  Inserting my 
bluetooth card yields the message: "RequestIRQ: Resource in use".  It's 
almost as if the pcmcia slots switched roles. :)

The VX88 uses yenta socket, and I noticed that your latest ChangeLog mentions 
a fix regarding multiple cards and irqs on a yenta socket, but this does not 
appear to be the same problem (or the fix was incomplete).

If this is an ACPI issue, how can I help resolve it?  I'm a competent 
programmer, and I have no problem with mucking with the source.

Thanks,
-Justin

Justin,
probably good to file a bug and work with David Shaohua Li on this one.
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI

component: Config-Hotplug

Please include the output from lspci -v, /proc/interrupts, and dmesg
-s40000

thanks,
-Len
