Just as an intermediate update on the issue, I've made progress and it hangs later down the line, see below: *************************************************************************=

Now searching for cause, looks like it's "init" related...
Wow... I just found out that it's not actually "hanging" at this point.. it's just working in "slow motion"... I found out by leaving the machine and coming back half an hour later to find additional output and eventually even a prompt. Here is what's happening: ************************************************************************* RAMDISK: gzip image found at block 0 VFS: Mounted root (ext2 filesystem) on device 1:0. Freeing unused kernel memory: 112k init <4 minutes pass> init started: BusyBox v1.7.1 (2008-04-02 09:14:47 MEST) <2 minutes pass> starting pid 403, tty '': '/etc/rc.sh' < etc... > ************************************************************************* I've tried a couple different ramdisk images (another one with a much older version of busybox), with similar results. Anybody have an idea about what's going on here?
