Just booted up pre91-1 after building it, went to build the floppy driver as a module and the system just fell silent. <Alt><Scroll> showed it was looping in swap_out_vma() in mm/vmscan.c Very repeatable (100%).
Backing out the patches to page_alloc.c and vmscan.c "fixes" the problem. I haven't the time to look at it in more detail now.
Easy to reproduce - just boot with mem=8m and compile floppy.c
[Side note: SysRq+u won't unmount for you when you do this, so be careful]
[Side note 2: SysRq+anything seems to leave the keyboard in an un-typeable state until you ALT+Fn to another console and back.]
