I was testing my r5k, 256 Mb ram SGI O2 again after some inactivity, and found 
what latest kernel (from LMO git, up to commit 
9368a0777aa3eaab13dcbd7038041df54885dc32
   MIPS: Fix __vmalloc() etc. on MIPS for non-GPL modules ) compiled with my 
usual kernel toolchain (binutils-2.19.1/gcc 4.3.3) will lock up/hang very 
early, even before  clearing screen.

Git bisect point me at some bootmem changes, last working commit for me is

Sorry for annoy you all on IRC, i'll try to add more interesting details about 
this hang as fast as my O2 finished some compile job i have running on it 
currently
