Under heavy load the Debian Kernel 4.14-13 crashes on high memory load and let the CPU freeze. Not really funny so rollback to older version
After Ubuntu published the latest Kernel Patches for Meltdown and Spectre the Kernel 4.4.0-104/109-generic let Intel Graphics freeze or hang on Compiz with Unity. Howto fix: Install the latest Kernel 4.4.0-112-generic do: sudo apt-get install linux-image-4.4.0-112-generic sudo apt-get install linux-image-extra-4.4.0-112-generic reboot then: sudo apt-get autoremove –purge -y This removes older kernels and save Space! Do test the PC for hanging again!!!
If you use Ubuntu Desktop 16.10 you will run sometimes into freezes of the Desktop with a Default Setup. Background: Theres a known Bug of the Deja-Dup Backup Service which is started by Cron. The Service take 100% Ram and 100% CPU usage. This did my PC with 16GB Ram too! Only HARD RESET helps to get back Control! Solution: Purge the deja-dup service with: $sudo apt purge deja-dup Use instead the “rsync” tool by command line with users crontab to Backup your User Homes to external or 2nd. Disk. This should fix the problem.
If you own a Gigablue TV Box ( Gigablue UE 800 2 Tuner DVB-S + DVB-C for example) a reboot on Firmware 4.2 can lookup the box to factory reset. This did my box too.

I found some Workarounds to fix (I have a gigabue with 2 Tuners inside and a HDD) To upgrade you need 3 USB Sticks 4GB FAT32 formated Go to the official Downloadpage and download […]
Today i was touched by a Bug of my fritzbox 7490, after installing a USB 3.0 Stick as NAS the Wifi connect was broken to all devices! After some search on net i found this post: http://avm.de/service/fritzbox/fritzbox-7490/wissensdatenbank/publication/show/1636_WLAN-Stoerungen-bei-angeschlossenem-USB-3-0-Geraet/ Background: The high magnetic frequency’s of USB 3.0 data transfer inside the cable or stick hangup the WIFI chips! It works like a WIFI JAMMER!! DONT USE A ROUTER AS NAS! If it fails or overheat all devices are offline!! It’s a really big joke that most Manufacter sell devices without TESTING!! I call it Banana Hardware..
