r8192ee-3.16rc4-armstrong.tar.gz Edit (183.9 KiB, application/x-tar)

I've been able to reproduce a similar problem to chuxinxin and collected logs.

Distro: Ubuntu 14.04 with Ubuntu mainline 3.16rc4
uname -a: Linux Cockatoo 3.16.0-031600rc4-generic #201407061635 SMP Sun Jul 6 20:36:26 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Step-by-step procedure to reproduce:
1. Boot system with r8192ee module blacklisted
2. modprobe r8192ee
3. Connect to wireless network with NetworkManager
4. Connection works well for a while
5. Connection suddenly disconnects
6. The wireless network is no longer visible in NetworkManager, but others remain visible.
7. Kill NetworkManager and wpa_supplicant
8. NetworkManager no longer shows device
9. Attempt to modprobe -r r8192ee renders system unresponsive

The attached tarball include lsmod, dmesg and syslog. I split the logs into before/after killing NetworkManager & wpa_supplicant since there was a lot of spam in the logs after that event.

It may be relevant that this was done in an environment with a lot of radio interference and dropped packets.
