yes, it is... the problem occurs intermittendly... sometimes after a few
minutes, sometimes after hours of runtime.

i should have appended the full dump which i did now. it shows that we are
running on a ps3.
no, we haven't tried it on a cell blade.

With 2.6.24 (your version from early february) the PS3 hangs completely...
you have to power cycle the ps3.
so, it looks like 2.6.26 is a little better... but you have to power off/on
as well to get rid of the zombie.
