[oe] Init fails with segfault on AVR32

[Alex]

Hi

While waiting for support from the mailinglist I tried a few more things 
to get my atngw100 system running.

I tried to use init from (statically linked) busybox. This will suffer 
the same problem but gives me a better clue where
the problem lies.

I found out that in a first step /bin/mount.util-linux is responsible 
for the segfault. And this is due to the shared library
"ld-uClibc-0.9.28".

If I replace this library with ld-uClibc-0.9.29 from atmel's buildroot. 
The segfault is gone!

There are rumours that some of you have OE running on ATNGW100 hardware. 
So what can I make wrong?
Can someone send me his local.conf?
I update OE from time to time in the hope this will save my problems.

I use:
- bitbake version 1.18.11
- monotone 0.31

And I update OE using the following commands:
 > mtn --db=/oe/OE.mtn pull monotone.openembedded.org org.openembedded.dev
 > cd /oe/org.openembedded.dev && mtn update

Hope someone can help me. I'm trying for weeks to get this stuff 
running....

Best regards,
Alex
