I can't see where it does this either, strange. That would be a very terrible bug if it's not invoking pending softirqs before return from system calls. Although, it might be happening via some clever side effect of how the software managed hardware interrupt stuff works on powerpc. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
