Hi!

I'm currently tryin' to get 2.5.x running on MIPS (for background,
please read http://www.lug-owl.de/~jbglaw/linux-ports/ ). I got current
CVS HEAD to build (with minor tweaks), but my Indy doesn't completely
load the kernel (via tftp). It starts loading the kernel, but TFTP
packet #3810 (containing bytes 1950208..1950719 resp. 1dc200..1dc3ff
from the kernel file) gets NACKed with error (5), code 3 (wrt. ethereal,
this is "Disk full or allocation exceeded"). After this, the box seems to
be completely dead: no serial break, no power button, no reset
button...).

Because 2.4.x basically runs on this machine, I suspect the linker
script changes. I've tried some older versions (added missing symbols
into them) to see if I can overcome these loading problems. Up to now, I
failed. Here's my kernel image's "objdump -h" output:

$ mips-linux-objdump -h indy-kernel

indy-kernel:     file format elf32-tradbigmips

Does anybody have some suggestions for me?
