problems with smartemedia

[Moises Beck]

Hi,
	I am trying to use a smartmedia card on a ppc MPC850 processor, running
a ELDK 2.0.2. A modified the file spia.c to corform it for the
parameters of my board. During the inicialization of Linux, it`s all OK,
where we can see:

...
NAND device: Manufacture ID: 0x98, Chip ID: 0x73 (Toshiba TH58V128DC)
Creating 1 MTD partitions on "Toshiba TH58V128DC":
0x00000000-0x01000000 : "SPIA flash partition 1"
NFTL driver: nftlcore.c $Revision: 1.83 $, nftlmount.c $Revision: 1.23 $
...

	But, when I try to mount the device, the kernel show the following
messages:

bash-2.05# mount /dev/mtdblock3 /mnt/nand

Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing

	Do someone have some idea about it ??
