Problem with PCMCIA on PXA255, Kernel 2.6.15

[Barbara Hughes <barbara.hughes@xxxxxxxxx>]

Hi,

I am experiencing a consistent problem with pcmcia on a pxa255/sa1111  
board which (by searching the archives)
 may be similar to a problem previously raised by Stefan Thomasson  
on 16th Jan, 2003, which seemed to be solved for kernel 2.5,
however I am experiencing the same problems using kernel 2.6.15.

When transferring in excess of 2Mb of data using a Orinoco Gold  
Wireless card (Cisco has also been tried), I get
the following message and sftp stalls.

NETDEV WATCHDOG: eth0: transmit timed out
eth0 Tx timeout! ALLOCFID=0127 TXCOMPLFID=03b1 EVSTAT=808b

hda: lost interrupt

In attempting to trace this bug we have included a 500microsecond  
delay prior to reading in
sa1111_irq_handler() in sa1111.c. We acknowledge that this is not  
ideal, but with this
addition transfers in excess of 2MB can be performed, with the number  
of failures described
previously greatly reduced, but still occurs without an identifiable  
pattern of occurrence.

Any advice would be greatly appreciated.
Barbara
