Please try the test kernel below. This will hopefully store the kernel panic information into persistent storage, so after rebooting to this kernel and waiting 30 seconds or so, reboot back to a working kernel and look in /sys/fs/pstore for a file with the name dmesg-ramoops-N, where N is a number. If you have one, please provide the contents of this file.
