So I've narrowed the regression down to a miscompilation (presumably) of net/ipv4/ip_output.o, in the sense that cp linux-2.6-gcc34/net/ipv4/ip_output.o linux-2.6-gcc43/net/ipv4/ip_output.o touch linux-2.6-gcc43/net/ipv4/ip_output.o make vmlinux fixes the issue. Unfortunately, the file is basically entirely different when objdump'd... The generated assembly is not much more help either. I'm going to try again with gcc 4.1 & 4.2, and hope they're similar enough that they generate closer assembly fragments... but, getting closer to a fix, I hope. -- To unsubscribe from this list: send the line "unsubscribe linux-parisc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
