No x windows and no network on reboot

[Bob]

When running ubuntu ibex 64, and after installing packages with apt, reboot give no X windows and no network. Possibly related to loading XV or similar libraries. Must re-install ubuntu once per day to get around this. Please do not mark as not a bug! I have been trying to determine which package is causing the problem, but little shows up in dmesg or in /var/log/messages or /var/log/kern. It makes 99% of ubuntu unusable (unless you really liked MS Dos 5!).

Please attach some debug information such as dmesg and your xorg.conf

SIOCADDRT: Network is unreachable is one message I got at one particular time. I traced it to a kernel module that both I (and the stock Ubuntu kernel) were loading (apparently, I don't know for certain about the Ubuntu kernel), as modules, instead of compiling into the kernel. When I built a new kernel with the module compiled in, my problems went away. I posted an update a day later (but I can't find the repost here on the forums). I've been running diffs on my kernel build files, but haven't isolated exactly which module it was. I still have compressed dmesg and kernel log files (which I am attaching). I could not ping anything beyond 127.0.0.1. My router is at 192.168.1.1 and I could not ping it.

Hi. I found some other information that I posted to another Ubuntu site. One of the error messages I did get (and I didn't get it most of the time) was: FATAL: binfmt_misc not found. I dug into the kernel I was building, and found that I had this built as a module. The kernels I built did exactly the same thing as stock IBEX kernels: after adding various pieces of software from official Ubuntu sources (via apt-get), and a reboot, my system would not be able to connect to the internet, and my X server would not start "Screens unusable". My only real solution was to rebuild the kernel with binfmt_misc compiled into the kernel (not built as a module). I did, and have not experienced the problem since. I don't know exactly why, but that is the solution. I have built several kernels with the same build file (with miscellaneous binary formats built in, instead of as a module) and have not had problems since. I haven't tried building new kernels with binfmt_misc as a module. It might be worthwhile to see if new kernels would cause the same problem, or if its been fixed. My system: Corei7/920 with X58 chipset, 12GB 1066/DDR3 memory, Nvidia GeForce 9600 GT. Its on an Asus P6T deluxe motherboard: Intel X58 Nehalem Core i7 QPI 6.4GT/s Tri-Channel DDR3 1600 LGA1366 ATX Motherboard w/ SLi / CrossfireX 3x PCI-Express 2.0 x16, Audio, GB LAN, SATA 3G/II, eSATA, SAS, RAID, USB 2.0, Firewire, ExpressGate. The GB lan is two Marvell Yukon gigabit ports (I only use one).
