It's better but still fails to find the IDE device. Interestingly, bisection firmly blames this patch and QEMU boots with the two patches reverted but fails with them applied so that patch does cause problems. The failure on the laptop must be depending on some follow-on patch. I tried a hatchet-job revert of the IDE patches between IDE-START and IDE-END in the series file and it similarly fails to probe the IDE devices. So either I made a mess of the reverts (strong possibility) or there is more than one problem patch. -- Mel Gorman Part-time Phd Student Linux Technology Center University of Limerick IBM Dublin Software Lab -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
