The git4 boots and > git5 does not boot. (Both based off 2.6.34.1.config) Yes, I had just generated this same diff.

So with CONFIG_ATA=m and CONFIG_SATA_AHCI=m, does 2.6.34-git4 boot but 2.6.34-git5 fails to boot? thanks, --- ~Randy *** Remember to use Documentation/SubmitChecklist when testing your code *** -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
