Openmips Enigma2 restart cron Gigablue

If you use a Gigablue SAT Box,after some weeks enigma2 will hang up:

edit root crontab:

$crontab -e

0 1 * * *   killall -9 enigma2 && sleep 5 && init 3 && /etc/init.d/samba restart
5 1 * * *   wget -O /dev/null -q "IP-OF-GIGA-Box/web/powerstate?newstate=0&type=0"

This will restart enigma2 Service, Samba and Webinterface too! Then Enigma is set to Standby!
That kodi can access the TV Bookmarks to view TV over LAN! If Standby is not set Kodi hangs!

Ubuntu Vivid Debian: Kernel I/O Errors SSD SATA NVIDIA Chipsets

If you use a PC with a SSD Drive and a Motherboard which uses NVIDIA chipsets you may see Errors on boot

Command „dmesg“ Output like..

This is a bug by the NVIDIA Manufacterer NOT by LINUX!

The Problem is that the hardware command „swncq“ (DMA-64bit) is set to on by the „default“ Kernels now, but older nvidia chips don’t support it! Only DMA-32bit

Info found here swnq libsata nvidia kernel (external Link)

Workaround on Gnome Terminal or Console:

  • $sudo echo ‚options sata_nv swncq=0‘ >> /etc/modprobe.d/sata_nv.conf
  • $sudo update-initramfs -u -k all
  • reboot and test with „dmesg“ command on Terminal! there should be NO Error now!
  • If the Problem still exists, then change SATA Cables to SATA-300/600 (II/III) „with Metal Clip on Connectors“ take „shortest length“
  • May be possible that this bug touches other OS like Windows too
