My target machine is an HP Jornada 720 (sa1100 based). Found this when trying
to boot from flashrom.
Using gcc 3.4.5 / glibc 2.3.5 memset.S is compiled without any errors. However
the kernel boots and freezes on memset.S (never returns from function). On
early_printk this is just seen as freezing right after "Node 0 : ..." message.
Using gcc 3.4.1 / glibc 2.3.2 works nicely.
