I just installed kernel 3.19.0-20 - the update appeared from the PPA.
Now it seems the keyboard is workingg better. Not perfect as you can see, but much better. Enough that I won't be returning this machine to Dell. Though I hope they issue another BIOS update with better de-bouncing.
It also seems to respond better if I bang hard when I type. My external keyboards are all mechanical switch, and I learned to type on a typewriter so many years ago, so I'm used to this.
Consider this resolved.
PS I got a kernel panic on wake from suspend on 3.19.0-20, so I reverted to 3.19.0-19. I suspended and woke 10 times in a row, no panics. Not proof, but I removed 3.19.0-20 and I'm sticking with 3.19.0-19, which I ran for 3 long days of work, multiple suspends, multiple wireless & ethernet changes, VPN, etc. with no panics.
I also installed A04 and a new kernel (3.19.0-20). But, the keyboard is still unusable--too many double letters. Does anyone know if some of the hardware works better than other samples? I'm planning on returning it--but my question is, should I trade it for a different piece of hardware in hopes it works better? Or are they all equally busted for people who type fast?
I can't answer your question but thanks for posting, at least I know I'm not the only one.
This must be a software problem, else it would have been noticed on the Windows version, which was reviewed by many different folks - someone would have noticed. Because of this it should only get better, not worse, as long as Dell knows A04 didn't fix it.
I have noticed that adding the kernel boot params has improved reliability - made the panics less frequent. I went back to kernel 3.19.0-20 and it's just as reliable as prior ones. My boot params in GRUB are:

After loading BIOS A04, I uninstalled then reinstalled kernel 3.19. This had no effect on the problem.
Current kernel is 3.19.0-19

GRUB_CMDLINE_LINUX_DEFAULT="pcie_aspm=force radeon.modeset=0 noveau.modeset=0"
GRUB_CMDLINE_LINUX="noquiet nosplash"
BTW, this typed on my external keyboard with Cherry browns - that's why no typos.
