PCMCIA on an MPC860

[Alex Zeffertt]

Steven,


Thanks for your reply.  I did try an ethernet card as well.  With that
I got a different problem -
after insmodding the client driver I got the following error message:
	eth1: command 0x5800 did not complete!

I also got this error whenever I tried to ping.


My Kernel IDE config is as follows:

# ATA/IDE/MFM/RLL support
#
CONFIG_IDE=y

#
# IDE, ATA and ATAPI Block devices
#
CONFIG_BLK_DEV_IDE=y
# CONFIG_BLK_DEV_HD_IDE is not set
# CONFIG_BLK_DEV_HD is not set
CONFIG_BLK_DEV_IDEDISK=y
(everything else IDE related is not set)

Here's my Oops:

Does this look familiar?  :-/

Thanks,

Alex
