Bug Description
The Linux kernel (on Ubuntu 11.04) crashes randomly. It may be a hardware failure because this laptop (Fujitsu Siemens AMILO Li 1718 laptop) is rather old.

It seems a memory corruption issue, but may still be a bug and not hardware issue. Can you boot your kernel with slub_debug kernel parameter (add slub_debug to GRUB_CMDLINE_ LINUX_DEFAULT in /etc/default/grub and run "sudo update-grub2", then reboot), and see if you get a different oops? If you get some other oops/warning with slub_debug then please attach here the dmesg output.
