I have that wifi card, under Lion 10.7.2, the problem is if I active it, in a few minutes I got KPs, if it's deactivated the system runs smoothly, it has an Atheros 5008 chipset, and I configured it under Airport.Atheros21.kext as 168c,23, but still have those KPs.

My configuration:
Intel DX58SO
i7 950
6Gb Kingston Hyper X
XFX HD6870 1Gb
2 Samsung 204UI HDs
TL-WN951N wifi

the board has an Intel Gigabit which is working fine, after I installed IntelE1000e

I am using a custom DSDT

and here's a link to my kernel's log >>> http://www.theoutletseason.com/kp/kernellog.txt

BTW my Gigabit Ethernet is configured as en0 and the wifi as en1.
