Well, I can reproduce it pretty reliably: it happens shortly after I up the iface and establish the WIFI connection with wpa_supplicant. A couple of minutes after that, more or less, the box grinds down to a halt. > I see from the dump that you have x86_64 architecture. How many CPUs > and how fast?

I don't think that has any effect on the wifi iface but here it is: dual core K8 laptop: ... processor : 1 vendor_id : AuthenticAMD cpu family : 15 model : 107 model name : AMD Turion(tm) Neo X2 Dual Core Processor L625 stepping : 2 cpu MHz : 800.000 this is of cource the lowest P-state freq - P0 is 1.6GHz. > Would you also try loading rtl8192se with the "ips=0" option?
