(The system won't boot right now, it wants a manual fsck first.) Bisecting this promises to take about 8 hours per iteration if I add up the wait for the hang, the fsck afterwards and the time this system needs for compiling a kernel, so I'll wait for you to tell me if it's really necessary. ;-) HTH Tilman - 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/
