I must also say, that my hope, that the wife problem has been solved with fwlps=0, was wrong. I can now even reliably crash my laptop with the following procedure:
* Wait till WiFi gets stuck * Turn off (soft kill) WiFi via KDE's network manager client * sudo rmmod rtl8723be * sudo modprobe rtl8723be * Turn on WiFi again via KDE. At the very moment of the mouse click to turn on WiFi, the screen freezes. In the attached log file, the times are as follows: * Turn off WiFi: 18:34:58 * rmmod: 18:35:13 * modprobe: 18:35:36 * Turn on WiFi: 18:38:17 ** Attachment added: "syslog excerpt for rtl723be crash" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1461174/+attachment/4428925/+files/syslog -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1461174 Title: Realtek Wifi card rtl8723be [10ec:b723] WiFi has an issue Status in HWE Next: Triaged Status in linux package in Ubuntu: Confirmed Bug description: My WiFi has an issue. --- ApportVersion: 2.14.1-0ubuntu3.7 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: u 1785 F.... pulseaudio /dev/snd/controlC0: u 1785 F.... pulseaudio DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=c2a5715c-c92c-47fa-9aa2-c6f6e03f21bf InstallationDate: Installed on 2015-06-09 (0 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) MachineType: Hewlett-Packard HP 455 G2 Package: linux (not installed) ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-30-generic root=UUID=97d2645a-a2be-49ec-b1bd-37c43ab4eeb1 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.16.0-30.40~14.04.1-generic 3.16.7-ckt3 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
