Hi all,
I've been workig with this for a while but have made no progress.
Today I got the latest XSysAce patch for kernel 2.6.17.1 and applied
it to get clean code.
I inherited the previous code from another developer.
Can you send the link to xsysace driver source code from where you obtained.
Thanks

My problem is that mounting the DOS partition always fails in a short
time with a kernel oops.

The setup:
My own build system.
Kernel 2.6.17.1 with lots of xilinx stuff, eth, i2c, xsysace.
Crosscompiled for PPC405.
Latest, clean XSysAce code. mods: major hardcoded to = 125. Polled
mode.
CF: 3 partitions,
1: DOS FAT16
2: Ext2 main
3: Ext2 rescue
This build boots up fine, mounts a ext2 as root fine. I can also
mount the rescue partition with no problems.
Does anyone have any pointers of where I should look for problems?
My next step is to go and set it up for interrupt service and see if
that changes anything.
Thanks,
Joe Robertson
