Created attachment 824891 [details] Photo of last kernel messages Description of problem: My Thinkpad W520 crashes on startup after upgrading to the latest F18 kernel Version-Release number of selected component (if applicable): kernel-3.11.7-100.fc18.x86_64 How reproducible: Always Additional info: The caps lock light is blinking after the crash. I get a lot of output when the kernel crashes. I've added a photo of the visible messages, I'll add the complete set of messages if someone can point me to some documentation on how to do this.
I'm guessing you are either missing an initramfs file for this kernel in /boot, or the grub configuration file is missing the "initrd" line for it. Can you verify you have a corresponding initramfs-3.11.7-200.x86_64.img file in /boot and that it's listed in the grub configuration file?
Yes, the initramfs was missing. Possibly because my 500 MB /boot is beginning to be too small to hold 3 kernels at a time.
