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. ** Attachment added: "r8192ee-3.16rc4-armstrong.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1239578/+attachment/4148033/+files/r8192ee-3.16rc4-armstrong.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1239578 Title: No wireless support for Realtek RTL8192EE [10ec:818b] To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1239578/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
