[ath9k-devel] Severe issue with ath9k_htc driver - consistent full system crash since 3.8 kernels

[Oleksij Rempel <linux@rempel-privat.de>]

Hi Dylan,

can you please provide some pictures of it?
One pic of the label, and if possible high resolution scans of pcb 
board.  Similar to this:
http://wikidevi.com/wiki/TP-LINK_TL-WN822N_v2
800 or 900dpi in jpg will be ok. Send it directly to me.
