Still no worky with kernel 4.8.0-1031. ** Attachment added: "Kernel panic with kernel 4.8.0-1031" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1667160/+attachment/4849159/+files/vlcsnap-2017-03-28-21h33m24s240.png
** Summary changed: - Kernel panic with 4.8.0-1025, -1026 and -1028 on RasPi 2 + Kernel panic with 4.8.0-1025 through -1031 on RasPi 2 -- 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/1667160 Title: Kernel panic with 4.8.0-1025 through -1031 on RasPi 2 Status in linux package in Ubuntu: Confirmed Status in linux-meta-raspi2 package in Ubuntu: Confirmed Bug description: I have a Raspberry Pi 2 running Ubuntu 16.10 without problems. I use wicd to let it connect to my WiFi with a RTL8188CUS USB dongle. And there's a RTL2838 DVB-T USB stick attached to monitor airplane positions for Flightradar24. After updateing the kernel from 4.8.0-1024, which runs flawlessly, to -1025, there's a kernel panic happening 10-20 seconds after booting up to the login prompt. I thought the -1026 fixed that, but it's still no worky. The trace is scrolling so fast I can't read anything but the last page: [<808c76c8>] (sock_sendmsg) from...
