I am having what appears to be a little conflict
with this driver, particularly with the MDR. My
hardware uses NAND flash and an FPGA connected
through the UPM. After the kernel is up and
running, sometimes I cannot verify the data in
the UPM RAM array. I am guessing right now that
this is due

Quick question. I have a 8313 based custom board. If I wanted
to include my config file and dts into mainline are there any
restrictions or requirements? Just curious.
Thanks, please let me know.

I wrote a custom driver for an MPC8313 based board. Everything seems to
have been working for a long time, but now one of my IOCTL functions seems
to be having a problem. I'm getting a Bus error reported by my
application and also a kernel Oops. Here's what the kernel is reporting.
Oops:

The system is up long enough to print an oops; you could
stick some output in the trap handler.
I have a custom board based on the MPC8313ERDB and have communications
capabilities over Ethernet using internet sockets. Basically, just data
transfer from the host (my board) to a client (a PC). I want to be able to
perform similar transactions across USB.
I have done some cursory reading

Hello all,
I got the latest kernel from git://git.denx.de/linux-2.6-denx.git and after
configuring with menuconfig I am seeing these errors. I feel like this

Thank you. That took care of it. I knew it was something small.

Scott,
I know I asked about this in the past, but I can't remember where it was left.
Did this get
resolved in some other repository that isn't the main linux-2.6 repository? If
it didn't I think
I might have a solution. BTW I'm using 2.6.26-rc8

Thank you for the help (again). I've got my driver registering the isr on it's
own now. In the
end the problem was the dts and also not using irq_of_parse_and_map.

So are you implying that the request_irq function should work without any other

You may want to try increasing the OR[SCY] field or

So are you saying that when this happened in the past
it was a timing issue? This change would need to
