Have you tested the latest patch? Any working .config file? I just tested it, seems can't boot. I have pushed the patch, along with my fix, to my git tree, so that the patch could be further polished. It is in linux-2.6.29-stable-ftrace branch. http://repo.or.cz/w/linux-2.6/linux-loongson.git BTW, it seems linux-mips@xxxxxxxxxxxxxxx is not an alias of linux-mips@xxxxxxxxxxxxxx, since I haven't seen our previous emails appear in linux-mips ML's archive. So I have added linux-mips@xxxxxxxxxxxxxx to CC list. When this patch is more ready to be included, we'd better include LKML in CC list, too. Because there are more ftrace gurus which could give advices to this patch.
