[Bug 1393744] Re: 1814:0301 RT2x00/rt61pci disconnects since update to 15.04

 

Having the same issue here as well (although I'm on Arch with 3.16
kernel). Interestingly, on the same computer running Mint (3.13 kernel),
there is no issue. With 3.16 kernel, RT61PCI works for some minutes,
then disconnects, and unable to reconnect again.

Note: both distro's use version 2.3.0 of RT61PCI.

dmesg on 3.16 kernel:
ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 0 failed to flush
