Hello, I have had this randomly occur on my Sun Fire V210. However
after switching to 3.11.4 I have never had this panic ever again so far.
If you have more than 4GiB of RAM, you will want to compile the kernel
without initrd support and use make-kpkg without --initrd, as the kernel
panics on boot with one.
