That sounds like you might be running into gcc PR27363. If you've built your old-ABI toolchain without a patch for PR27363, you _will_ run into issues of this kind. > It may be due to the way the structures are packed. Shouldn't matter -- if you use a gcc 4.1 that defaults to old-ABI to compile your kernel but pass it command line options to set the ABI to aapcs-linux (i.e. EABI, like the linux kernel build does), it should work. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
