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.
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
