Comment 128 for bug 286285

Hi, I'm using 8.10 64bits on a Lenovo Y530 with a intel 5100 and nvidia 9500M GS card. I've got exactly the same bug than the others ones : dd and klogd eating all of one of my cpu core. My system is up to date and the bug seems only to occur when I'm using wpa2...
dmesg show me a lot of :

I've joined my dmesg log.
Btw I got strange behavior from times to times, kernel panic at boot (see dmesg.0), and sometimes the wireless card need to get a ifconfig wlan0 up before working...
