Just for reference I build that code with: arm-unknown-linux-gnueabi-gcc (GCC) 4.5.2, GNU ld (GNU Binutils) 2.21 and it was fine so I don't think it's to do with the switch from arm-linux-gcc to arm-unknown-linux-gnueabi-gcc[1] Yours Tony [1] This switchwas done as a result off the discussion at: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-November/030627.html
