[Kernel-packages] [Bug 1568865] Re: [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] *ERROR* CPU pipe B FIFO underrun
Actually I just tried the 4.6 kernel that was officially released 2 days ago, and I still get a freeze when attaching monitor to HDMI.However the symptoms are different. The external monitor does get the desktop drawn on it, and I can move the mouse around, and between the monitors. But the interface is otherwise frozen: the clock on the screen stops "ticking" and no windows can be interacted with. Also cannot hit CTRL+ALT+F3 to get to a tty screen. Furthermore the logging in syslog is different: May 18 13:29:58 squan /usr/lib/gdm3/gdm-x-session[1313]: (--) intel(0): HDMI max TMDS frequency 30KHz May 18 13:29:58 squan /usr/lib/gdm3/gdm-x-session[1313]: (II) intel(0): resizing framebuffer to 7680x2160 May 18 13:29:58 squan /usr/lib/gdm3/gdm-x-session[1313]: (II) intel(0): switch to mode 3840x2160@60.0 on eDP1 using pipe 1, position (0, 0), rotation normal, reflection none May 18 13:29:59 squan /usr/lib/gdm3/gdm-x-session[1313]: (II) intel(0): switch to mode 3840x2160@30.0 on HDMI1 using pipe 0, position (3840, 0), rotation normal, reflection none May 18 13:29:59 squan /usr/lib/gdm3/gdm-x-session[1313]: (--) intel(0): HDMI max TMDS frequency 30KHz May 18 13:30:04 squan systemd[1]: Starting Stop ureadahead data collection...

[Kernel-packages] [Bug 1305305] Re: 8086:08b1 [Sony VAIO SVP1321M2E] Wifi keeps dropping.
David Carter - that's no good! My guess would be that you now have a missing firmware problem. Run the following command in a terminal: "ls /lib/firmware/iwlwifi-7*" you should have at least one file listed. I actually have two: /lib/firmware/iwlwifi-7260-7.ucode /lib/firmware/iwlwifi-7260-8.ucode If you don't then you definitely have missing firmware . If you do have a file, you might not have the correct one for your edition of the wireless card. Note that I upgraded to Ubuntu 14.04 (rather than clean install), and I had put the -7.ucode version of the firmware file in place months back in order to get the card to work at all (the older kernels didn't support this card at all). Here's a summary of how I installed backports for this card and the firmware: Download the ucode file for the 3.13 kernel here: http://wireless.kernel.org/en/users/Drivers/iwlwifi?action=AttachFile&do=get&target=iwlwifi-7260-ucode-22.0.6.0.tgz#Firmware Download backports for 3.13 here: http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/ Un-tar the downloaded files: tar xvf backports-3.13.2-1.tar.xz tar xvf iwlwifi-7260* Then build backports for iwlwifi cd backports-3.13.2-1/ make defconfig-iwlwifi make sudo make install Then copy the firmware ucode file to /lib/firmware cd .. cd iwlwifi* sudo cp iwlwifi* /lib/firmware -- 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/1305305 Title: 8086:08b1 [Sony VAIO SVP1321M2E] Wifi keeps dropping.

I can confirm 24 hours of goodness after installing backports 3.13.2-1 on top of 14.04 .

I downloaded and built backports 3.13.2-1 since posting my last comment. After rebooting, and so far, wireless seems much more stable and speedy.

[Kernel-packages] [Bug 1305305] Re: 8086:08b1 [Sony VAIO SVP1321M2E] Wifi keeps dropping.
I have the same problems. I'm on a Sager laptop with an Intel 7260AC . Worked fine for months (since last September) with previous releases (had used backports and was most recently on kernel 3.11.0-20 before upgrade to 14.04). Connection now exhibits: slowness (sporadically), drops (anwhere from 3 minutes after connecting to 2 hours after), and loss of connection after screen timeout lock and logging back in (which may just be the same problem as the time). When in the state of the connection having dropped, the listing of wireless connections available to connect to shows all of my neighbors' routers, but not mine. Disabling wireless connections and then immediately re-enabling will re- establish the connection for 2-120 minutes. I will also note that when initially connecting, I will have good signal strength indicated in the status widget (e.g. 3-4 bands) but that after some minutes it shows weaker (1-2 bands). All this without moving the physical location of the computer (distance to router). -- 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/1305305 Title: 8086:08b1 [Sony VAIO SVP1321M2E] Wifi keeps dropping.
