I have AMD Athlon XP1600+ with 623 MB of ram.

It was running fine with kernel 2.6.32-31-generic until I installed the latest updates. After updating Ubuntu requested to restart the computer. As soon as the computer boots, the system crashes immediately, starting up, crashing, also.

When a key is pressed, the Grub menu appears. After selecting the kernel 2.6.32-31-generic the system boots normally.

Both 2.6.32-32 entries (normal and recovery) are crashing. There are no visible entries in the log-files made. What can go wrong? How can I figure out what is going wrong?

  • Current Version is not 2.26.... but uname -a Linux Ubuntu-Bernard 2.6.32-31-generic #61-Ubuntu SMP Fri Apr 8 18:24:35 UTC 2011 i686 GNU/Linux. I can successfully boot from a live-cd with a more recent kernel, eg. Linux Mint: uname -a Linux mint 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 athlon i386 GNU/Linux – Bernard Decock May 30 '11 at 18:07
  • Try removing `quiet` from the `linux` line in the Grub boot entry, and report the last few messages you see on the screen. If you're feeling more ambitious, check the [kernel debugging guides](https://wiki.ubuntu.com/Kernel/Debugging). – Gilles 'SO- stop being evil' May 30 '11 at 19:00
  • Gilles. Thank you very much for your advice. I removed "quiet" as well as "splash" and added the tag "debug". After pressing Ctrl-x the computer crashes instantaneous. (No logfile /tmp/initramfs-debug was created). – Bernard Decock May 30 '11 at 20:45
  • I checked the boot-directory for potential "abnormal" files. Everything seems fine. The config-files of both kernels have only a slight difference :diff config-2.6.32-31-generic config-2.6.32-32-generic 3,4c3,4 < # Linux kernel version: 2.6.32-31-generic < # Fri Apr 8 18:24:23 2011 --- > # Linux kernel version: 2.6.32-32-generic > # Wed Apr 20 21:54:15 2011 74c74 < CONFIG_VERSION_SIGNATURE="Ubuntu 2.6.32-31.61-generic 2.6.32.32+drm33.14" --- > CONFIG_VERSION_SIGNATURE="Ubuntu 2.6.32-32.62-generic 2.6.32.38+drm33.16" 124c124 < CONFIG_NET_NS=y --- > # CONFIG_NET_NS is not set – Bernard Decock May 30 '11 at 20:46
  • This question should instead be filed as a bug report, and [as such](http://meta.askubuntu.com/questions/1317/what-to-do-with-questions-that-describe-known-bugs/) is off-topic, thanks! [Instructions here](http://askubuntu.com/questions/5121/how-do-i-report-a-bug). – jrg Feb 01 '12 at 18:16
