Hi Bert!
Ah, this is your clue, here: looks like the kernel ran BUG() or
otherwise failed at address 0xc071b594... can you send your .config and
I can see if I can reproduce? Your System.map should indicate what's at
that address, to...
I should really try to read out the BUG info in this case; I'll patch
something up today (I'm chasing James Morris' initrd bug at the moment).
Thanks!
Rusty.
