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 A15 07/11/2013 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1063035 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.
