I was able to boot linux on my rx1950 with recent haret (and modified PHYSOFFSET_KERNEL, as I need it to get resume working). The problem was in uninitialized uart. Kernel hangs if it uses ttySAC0 for console, but ttySAC0 was not initialized. AFAIK this bug in kernel was already fixed (in 2.6.30 or 31, not sure). As a workaround I've added uart initialization to bootLinux function. There're two patches in attachment, first one adds proper RX1950 detection to haret, second one is workaround I've used. Please consider applying of first one. Regards Vasily
