this message is incomplete. I assume there was some hiccups on chip reset.

Usually my adapters was not able to boot if there was problem with chip 
reset. Beside, only one case, where i get corrupt buffers and chip was 
misconfigured after reboot and firmware upload.

May be it is that case. Please test this firmware:
https://github.com/olerem/open-ath9k-htc-firmware/commits/suspend_fix

with this kernel:
https://github.com/olerem/linux-2.6/commits/github-wifi-ath9k_htc-fw
Or you can try to apply my patches on your kernel.

This firmware is not compatible with other kernel version. It wont work 
without my kernel patches. And this firmware has an issue with "ifconfig 
up"... so don't bring it up for now.
