Hi Steve

I haven't found the time to test the newer release but i still have some 
feedback for the "older" stuff.

Well i just found out, the error is still present :-(. The process start of 
reboot sometimes just fails with a "Bad address" error. I think this behaviour 
is there in all 3.0.x-rt releases. This is on arm i.xm35 pcm42 platform. I 
currently have no Idea where this error comes from but i would be happy for 
any input. I suspect that this error is happening with other processes than 
reboot. I suspect that failing konqueror ssh client sessions with "fish://" 
also are failing due to this error. Unfortunatly no hard evidence for this.

Best regards
Tim
