Are you having a problem with debug w/the 64-bit kernel? The 32-bit kernel supports several kernel level debug features that the 64-bit doesn't support. So if you are having an issue that might be more helpful to convey that just asking about exception code path. - k _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
