It breaks pmac netboot during the jump from __secondary_stat() to clear_bats(). There must be some I mappings we need to preserve in order to get to non-pc relative code. It's worth noting that OF loads us and gives us mappings for 0xc000000 since that's where we're linked at. BootX and Quik don't do that so that's probably why they work. Netboot is really useful so I'd prefer to not break it (definitely not in 2.2). Any ideas for workarounds? Chrp and prep netboot works fine. Boot via quik on chrp works, too. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
