Correction: it is a Dell Latitude D600. After searching around, it seems like this problem has something to do with PAE support compiled into the server kernel. I was able to install a working kernel by booting from the server install CD, launching a recovery shell, and running apt-get install linux-generic
When booting, press ESC to enter the GRUB boot menu and select the -generic kernel (probably the third one in the list). (Even better, you can edit /boot/grub/menu.lst and make this the default kernel.) This is the easy way out. Those feeling more adventurous can compile the server kernel without PAE support. -- PANIC: CPU too old for this kernel https://bugs.launchpad.net/bugs/151942 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
