Hi Ameet

I have posted a few messages regarding Ssytem ACE driver for Linux-2.6.

We are working on a AMCC 440SPe based custom board.

We applied the patch from

http://www.cs.york.ac.uk/rtslab/demos/amos/xupv2pro/patches/linuxppc-2.6.17.1-sysace-1.2.patch
 and applied against 2.6.16-2 kernel.

We are trying to make the driver work in interrupt mode.

First, I would like to know if the driver tested in interrupt mode.

We are able to mount the CF, but it is very inconsistent.

Same is the case with fdisk command. When it fails,we get errors which you could see in the screen-dump below.

Are we missing to apply the right patch? Please let us know your inputs to go forward.
Looking forwards for your reply.

Thanks
Junita
