[Voyage-linux] kobject (cec84330): tried to init an initialized object, something is seriously wrong

[Jean-Pierre Schwickerath]

Hello 


I'm testing the update to voyage 0.6.1 from a 0.5.2 setup where I run
asterisk with a Xorcom USB 4BRI connected to an Alix-Board. 

I made a fresh install of 0.6.1 and installed zaptel_1.4.11~dfsg-3_i386

When I connect the astribank I get a scary message:

 =======================


I tried various firmwares (those of zaptel 1.4.11 and 1.4.12) but
the kernel dump persists. I also noticed a few lock ups of the whole
system after plugin in the astribank. 

Which part is broken? The kernel itself or the zaptel drivers? Or is
the firmware not compatible with the 2.6.26 interfaces?

Does someone have a hint where I should start fixing the issue?
