If you check the release notes for the "A15" BIOS and the intervening
updates, there are almost no fixes included, and certainly nothing that
would relate to WiFi, the PCI/PCIe buses, or anything else conceivable
that would impact this problem. Nonetheless, I've upgraded to every new
BIOS release within a week of posting to the Dell site.

It's persisted across: Quantal -> Raring; repeated kernel updates (both
xorg-edgers and Ubuntu mainline); BIOS updates; two Intel 6300 radio
parts; one Intel 6205 radio part; one Intel 6235 radio part; many WiFi
networks; the 2.4GHz US ISM band; the "5GHz" US U-NII bands; many access
points from many manufacturers.

I'm not sure what you mean by "what happened." I thought the Red Hat bug
report described the problem quite thoroughly. If you mean what happened
after I applied the A15 BIOS update or any of the others, the answer is
"nothing visible." I only bother to apply new BIOS releases given the
knowledge that almost no OEMs disclose when or if they enclose new Intel
or AMD CPU microcode bundles in new BIOS images.

I don't know if you expected this information to differ from the Dell
release notes, but it doesn't:

localhost ~ [0]# dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Title:
  [xorg-edgers] iwlwifi connection freezing on xorg-edgers kernel

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm experiencing the problem referred to at
  https://bugzilla.redhat.com/show_bug.cgi?id=785561#c4 . This problem
  is severe enough to completely kill WiFi connections on heavily-loaded
  networks.

  The xorg-edgers bug reporting guidelines are very unclear, at least
  about kernel-related problems. I apologize if this is the wrong place.

  Does anyone know if this bug has been solved in the stock Ubuntu
  kernel, and whether the xorg-edgers kernel for precise (or any Ubuntu
  kernel) has absorbed the fix? I've tried fiddling with a lot of
  iwlwifi modprobe options, and none reduce or eliminate the problem.
