My apologies, Johannes. I made some unwarranted assumptions about register usage in the lowest-level exception handlers. While it worked on my 7447 board, I saw similar random failures on the 85xx (booke) system I tried. Thanks for testing this. I'll follow up with a revised patch. -Dale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
