(I will rebuild it if needed) However I can still provide some info: - kernel panic while loading modules, just after loding ZFS module (I have RAIDZ configuration) and after a couple of minutes without any visible action on the screen. - I have this panic with *every* build I made after 7 Dec 2008, but I don't remember wchich day exactly I have experienced that for the first time. - For now I'm using kernel builded 7 Dec 2008 and no panic seen at all. -- Bartosz Stec
