<title>XSysAce driver cant mount DOS part</title>
<!-- Converted from text/plain format -->
<p><font size="2">Hi all,<br>
<br>
I've been workig with this for a while but have made no progress.<br>
Today I got the latest XSysAce patch for kernel 2.6.17.1 and applied it
to get clean code. <br>
I inherited the previous code from another developer.<br>

Can you send the link to xsysace driver source code from where you
obtained.<br>
<br>
<br>
Thanks<br>

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

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