I wasn't able to catch anything using IOMMU, and I also wasn't able to reproduce the issue using any userspace memory checking tool. Hence I tend to believe we're not dealing with a memory corruption at all, perhaps something like certain CPU flags/registers not being correctly saved/restored during wlan interrupts or something. When I have a sufficient amount of free time, I'll try to check this hypothesis and perhaps pinpoint the instruction the result of which is corrupted during wlan operation. > Tomáš, I do not remember, do you have the same problems on > older kernels i.e < 3.0 Yeah. I was able to reproduce it with 2.6.38.8 and 2.6.39.4 at least. Regards, -- Tomáš Janoušek, a.k.a.
