Title:
Kernel crashes in rt2x00queue_get_entry+0x24
Status in linux package in Ubuntu:
Confirmed
Bug description:
When using an Logilink USB WiFi stick reported as Ralink Technology,
Corp. RT5372 Wireless Adapter, I ancounter frequent disconnects
despite good wifi signal, and repeated kernel crashes at
rt2x00queue_get_entry+0x24.
The crash may happen from time to time, but can be provoked by heavy
wifi traffic.
Maybe it is a problem with the drivers state management, because dmesg
shows resets or replugs of the device if temporary disconnect happens.
So I think the device may reset due to other problems (eg. flaky usb
power), and the driver doesn't handle it well in all states. Maybe the
above function is called with the device already disconnecting.
