Pierre, I actually tried to check for this kernel bug (OOPS) on the latest vanilla kernel and I wasn't able to reproduce it (with my test powerpc64 lpar), so let me manually update kernel on gcc203 to the latest vanilla stable (something like v6.12-rc4), up until more recent debian sid/unstable kernel package is available.
I'll send an update on kernel installation. Thanks.
