卡死现象不是必现的,不定时的出现,也没什么规律。上电启动,load模块,ifconfig wlan0 up网卡,偶现该问题。出现这个现象时,sdio时钟正常,模块外部32.7K时钟正常, reg_on电压正常。尝试升级驱动版本为100.10.545, 问题依旧。在写wifi模块固件时出现,固件时分多次由主控写入模块。有时候第一次写出错,有时候写入几次h

内核版本:3.10.14+ #18

最新log,主控向wifi模块写入数据过程中卡死。(另一种是刚开始写数据就卡死,不会打印该行log[ 6.703895] dhdsdio_membytes: write 4 bytes at offset 0x00007ffc in window 0x00078000)
