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

Thu Apr 23 01:49:39 HKT 2009

Hi Punky

> May be you can blacklist the xpp-usb modules and try.

The problem is that I *need* the xpp-usb module because the astribank
I try to connect uses it. 

In the meantime, we compiled we checked with a regular debian lenny and
have the same behaviour there too. So as it's not Voyage specific, I'm
gonna check with Tzafrir, the author of the astribank drivers and see
what we can find out.

Thanks anyway for the hint.
