hi, all My platform equipped with a wl1271 wireless chip. The system crashed randomly with following error messages when reboot the system with wifi enabled. >From the log, i found that there is a sdio_bus_remove function call in the stack. I'm confused about that. Does anybody know what happened to my driver?
