>Description:
With latest FreeBSD 9.0-900036-CURRENT #0 r221612M: Sun May 8 12:10:51 VLAST 2011 I've got too unstable wireless in my laptop with AR9285 card.
After 1.5-2 hours of online work, it lost connection. Any attempts to restart wireless produce next lines on console until reboot:
May 8 15:24:21 Beastie kernel: [ath] Warning - initial NF calibration did not complete in time, noisy environment?
May 8 15:24:46 Beastie kernel: ath0: device timeout
Reverted to kernel r221369M, which is more stable.
