I tried to debug another problem and turned on most debug options for memory.
The resulting kernel failed to boot.

Bisecting the configurations led to CONFIG_DEBUG_VIRTUAL - if I turned it on
in addition to some other debug options, the machine crashed with

kernel BUG at arch/x86/mm/physaddr.c:79!

The machine was Athlon XP with VIA KT600 chipset and 2G RAM.
