After upgrading to > A04 the problem went away and now everything works fine. Very good. I suggested this because the PW 380 is a poster child of the buggy BIOS, and also of industry involvement: Dell fixed the problems for us. Buy a beer for Matt Domsch. Here's the original RHEL bug (do not add silly comments or I'll make it private): https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=165749 Notice that the bug deals with broken sharing between EHCI and its companion controller. This is also something a BIOS breaks often. But you should've seen wild theories people posted about it to Ubuntu forums, they just crack me up. -- Pete - 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/
