It's a bug which should be fixed but nevertheless I can highly recommend something like a SiliconImage SATA controller - the onboard PIO PATA controller is so slow. > I narrowed the file changes to > > arch/mips/mm/c-sb1.c > arch/mips/mm/cache.c > arch/mips/mm/init.c > include/asm-mips/cache-flush.h > include/asm-mips/page.h > > between 2.6.16.27 and 2.6.16.29.
