So it doesn't look like a memory corruption after all. It
seems as if certain CPU instructions didn't work properly if running on a
32-bit kernel with a WiFi adapter doing something. But how can it be
that those same CPU instructions work on a 64-bit host with 32-bit userspace?
At the same time! That's just completely insane, and I can't think of an
explanation. Shall I get a new CPU perhaps? :-)


Please, give me any ideas that you might have.

That make sense! Your "CPU instructions break things" theory sounds crazy,
but I think it's logical. WPA enterprise differ from WPA-PSA (pre shared
key) that the key changed periodically, SSL is used when keys are changed
(via wpa_supplicant). So looks like 32-bit openssl generate object code
that trigger bug on CPU, which crash other processes.

It seems that someone beat me to it. Since Linus fixed the FPU leaks in
3.3-rc4, I haven't experienced the problem. And I was this close! :-)

Anyway, thanks for assistance and sorry for being so slow to respond.

Regards,
