Well, crap. I guess this was bound to be an issue sooner or later. Thanks for doing the investigative work. Looks like we're going to have to go down the road of blacklisting known bad machines after all. I was reluctant to push for that originally as the result of missing a machine from the blacklist might result in said machine becoming bricked, but we've now got patches in place to turn off the pstore efivars code, and I suspect that most distros indeed do that. -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
