我在使用atheros驱动程序时遇到了一些问题。我使用ad-hoc连接将立体相机中的图像数据共享到其他计算机,但有时会断开连接。

使用" dmesg"命令:

[ 9972.163572] ath5k phy0: no further txbuf available, dropping packet
[ 9982.198551] ath5k phy0: no further txbuf available, dropping packet

我已经从其他来源(例如https://bbs.archlinux.org/viewtopic.php?id=88765)读到这个问题可能是驱动程序的内部问题,并且已经制作了补丁,但我担心我的内核版本应该已经解决了这个问题。

我的内核,来自" uname -a":

最后," lsmod"也可能对你有所帮助:
