As long as we pick one of the patches (or a third > one) within a bound amount of time we should be fine :) I'll defer to Rafael here; he's been working the most in this area. The changelog wasn't very complete for the original patch, but it sounds like in the kexec case the newly booted kernel will get an igb device in D3 which it can't handle? That really does sound like a driver bug, not something we should mess with in the core. -- Jesse Barnes, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
