So I might have trouble bisecting, as stone-age kernels don't seem to boot on my installed system cleanly any more; some kind of incompatibility with my encrypted partitions. But I booted an F16 live image, which has kernel 3.1.0, and that reboots quickly. If I'm reading things correctly, mjg59's patch went into kernel 2.6.39, so if that was causing the problem, I'd expect the F16 live image to have a slow reboot. I'll go back through the live images for F17->F19 and see when the reboot gets slow, which will give us a very rough range to look at, at least. I'll also try Rafael's suggestion re acpi_osi. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net -- 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/
