reiserfs: badness at fs/namei.c on powerpc with kernel 2.6.30-2-powerpc64-smp

[Matteo Settenvini]

Attaching my dmesg log file. I'm still using 2.6.30-2-powerpc64-smp, because all newer kernels either lack some modules (the windfarm ones) or, with the most recent kernels, the system hangs just after the kernel starts loading. It reports:
