Bleeding edge is anything which hasn't been in use long enough that there is still significant potential for major bugs. Having had very long experience with the Linux kernel (and having fixed the bugs myself on several occasions), the 3.x kernels qualify. Anyway according to your description you are loading binary blobs into your OS, so you just voided our support and this bug report can be closed away unless you can reproduce without. 1- Actually, VMWare provides the source code for their kernel interface code which uses loadable modules, but usually someone has to work up a source code patch for the latest versions of the kernel ( 6-9 months old) and then users have to patch and rebuild the kernel interface. I have worked up patches myself on a few occasions, but I don't really have the time. 2- I wasn't running VMWare at the time I reported these problems, I use it only for customer software development and there weren't any customers back then. Now I am rather busy. So no, this bug report cannot be closed on that basis and as I stated before, even a cursory scan of the internet shows this is a common problem for people running similar hardware, so even if I were running binary blobs, the bug should remain open. NOTE: If one were to assume that VMWare were in any way relevant to this problem, then the bug should move from machine to machine as I migrate my development environment. Instead, the bug showed up when I moved to a new machine with different hardware and device drivers, but the same kernel. I upgraded to a variety of different kernels in the hope that one of them would work and have settled on the current one I am running because it seems to have the problem less often. Shannon C.

Bug#628444: linux-image-2.6.39-1-686-pae: iwlagn - MAC is in deep sleep, cannot restore wifi operation
A developer at Intel contacted me regarding this bug the other day (he was following up on a similar bug report from another source) and I am working with him on the problem (currently doing a debug build of the module to collect data on what is happening).

Bug#628444: linux-image-2.6.39-1-686-pae: iwlagn - MAC is in deep sleep, cannot restore wifi operation
Package: linux-2.6 Version: 2.6.39-1 Severity: important After some arbitrary period of use, wifi fails and errors show up in syslog indicating MAC is in deep sleep after which nothing can be done to restore wifi functionality other than rebooting the system. In most (possibly all) cases, the failure occurs after the laptop has been suspended and resumed at least once, though the actual occurance may not be immediately after resuming, it often occurs within a few minutes after resume. Unloading and reloading the iwlagn driver and the drivers it relies on have no effect. Speculation: there is a mechanical switch on the side of the laptop which cuts power to both bluetooth and wifi on this machine. Unloading iwlagn turning off the switch waiting ten seconds, then turning it on and reloading iwlagn also has no effect. Assuming this switch actually is a hardware power off of the devices, this should reset the device and a reload of the driver should restore functionality. Since this does not occur, I see only two possibilities, either the power switch does not completely power off the device, or the kernel is retaining some bogus information (possibly placed there by iwlagn) about the device in spite of the driver being unloaded and reloaded. Even if it doesn't prevent the problem, simply curing this issue so the device can be restarted without rebooting would be a major improvement. I have tried a number of different versions of the firmware as well as different kernels, all combinations have the problem, though some seem to be more stable than others. In some combinations it make take one to two weeks of usage with perhaps a dozen suspend resume cycles per day, in others it seems to happen every day. I have noted in my search of the net that Lenovo laptops seem to be most (possibly all, I wasn't paying close attention) of the cases where this bug occurs. My system is a Lenovo x201i, the wifi adapter was listed as an: Intel Centrino Advanced-N 6200 (2x2 AGN) This bug actually applies to all Debian kernels I have tried including 2.6.36, 2.6.37, 2.6.38, and 2.6,39 (various versions of each and I think it included earlier ones, but I don't remember which ones and no longer have them installed). NOTE: this appears to be the same as closed bug 589383 which was closed upstream and tagged unreproducible. Even the most cursory search of the net shows there are lots of people having no problems reproducing it. It strikes me as inappropriate to close a bug as unreproducible when it is quite clear that many people are seeing it.
