I second that. I've got a 2522-W29. And many others are out there suffering from that issue. Please fix and provide an updated BIOS.

since we dont have more info, do you guys have this entry in dmesg on lenovo g470 :
"\_SB_.PCI0:_OSC invalid UUID"
please report your model and bios version
is this related to our ASPM issue ? and can this be fixed by replacing DSDT ?
