Hi All,
I am porting IDE drivers(Since my hardware has endian issue),
and now it could work,however it has some abnormal problems:
I could 'fdisk' /dev/hda,and partition it into several partitions.
After this,I reboot my board and see all the partitions is there.
Then I 'mke2fs' on /dev/hda1,after this, when using 'fdisk' again,
I found all partitions gone! At this time,I could not access /dev/hda1
any more.However, I could 'mount /dev/hda /opt', it really worked,and
I could create/read/write/erase files in it.
I dumped the first sector of Hard disk and found that it has been
zeroed.Now I dont know what the problem is,since I am not familiar
with fs parts of linux kernel,and I dont know what 'mke2fs' has done.
Any advice?
Alan

Kaffe's makefiles won't pick up on configuration changes, so any time
you re-configure for a different engine or debug level, you need to do
a make clean. At least, that's the way it was the last time I worked on it.
If you had a partial build with JIT, then changed to intrp, then you could
get all kinds of strange behavior. The address range of your error us a
dead giveaway. It's too high to be the kaffe code segment, but too low
to be a shared library. It's where I'd expect the heap to be, and where
I remember the JIT buffers being allocated when I was trying to debug
that stuff.
