We don't want to have a fix in the kernel for *every* erratum if it can be helped. We're making an exception for this one because it can freeze the core just by executing a locked insn which can be done even in userspace. > @Boris: Could you please create a branch at bp.git with your patch so > I can base my work on top of it? For future AMD patches, make sure to almost always use tip master, i.e. git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git#master to base your work off of. > Also, I tested this patch against linux.git on a fam16 based machine > and it works fine. Thanks, much appreciated. I'll add your Tested-by. > (I wasn't sure if you had access to a fam16 based box) Yeah, I don't. So I'm relying on you for future patches :-) Thanks. -- Regards/Gruss, Boris. Sent from a fat crate under my desk. Formatting is fine. --
