I tried to bisect the bug, which failed because there were too many kernels not booting with other problems, I guess bisecting just fails in the merge window. With CONFIG_SLUB_DEBUG_ON the output looks different, unfortunately netconsole stops before those are transmitted. As there are always some lines about e1000 in the backtraces, I tried to boot without LAN cable connected, and it worked, and crashed afterwards when I plugged the cable in, with a bug in net/core/dev.c. I will search on tomorrow, as it is getting quite late now. Should I copy the messages with CONFIG_SLUB_DEBUG_ON by hand, or are just some parts important? cu Dieter -- 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/
