[Bug 95877] feisty: kernel oops after unplugging and replugging wlan-dongle

Sun Mar 25 12:23:59 UTC 2007

Public bug reported:

recently installed ndiswrapper from repos. dlink-dongle is plugged in,
driver installed. no wlan0 shows up, even though ndiswrapper -l shows
driver installed/device present messages. so i unplugged and replugged
the dongle which led to a kernel oops. reproducable every time.
