Comment 24 for bug 1238194

Will someone please "explain to me like I'm 5 (in computer years)" why this was necessary? What's going on? When I upgraded to 13.10, my keyboard stopped working completely after GRUB, and I'm left an "(initramfs)" prompt without a working keyboard. I had to boot an older kernel (thank goodness I had one!), append "ohci_pci" to /etc/initramfs-tools/modules, then run "update-initramfs", and I don't know anything about what any of those steps do, what ohci_pci is, what initramfs is, or why these steps were required.

Thanks!
