Title:
Panic in rt2x00lib
Status in “linux” package in Ubuntu:
Expired
Bug description:
This panic has been occurring intermittently and unpredictably on a
gateway/router/WAP server since enabling 802.11n in hostapd which uses
a Linksys WMP600N. The server has 6 gigabit and 4 fast ethernet ports,
the Wifi, and a xDSL port.
The kernel panic was captured over a serial console since the server
fails to sync when the panic occurs and no indication is captured in
the logs.
