RPi3 + apt-get upgrade -> lots of continuity errors

Stefan N.

Hi together,

I did an "apt-get upgrade" of my Raspbian Strech Lite from (2018-04-18) and now cannot use TVHeadend any more. I have 2 Hauppauge PC-TV 461e USB sticks that worked fine so far (firmware dvb-demod-m88ds3103.fw from Hauppauge servers), but now produce tons of continuity errors, hundreds in a few seconds, streams are stuck and unwatchable. During the upgrade, the following packages have been touched:

* bluez-firmware
* ca-certificates
* curl
* dpkg
* dpkg-dev
* file
* firmware-atheros
* firmware-brcm80211
* firmware-libertas
* firmware-misc-nonfree
* firmware-realtek
* gnupg
* gnupg-agent
* gpgv
* libcurl3
* libdpkg-perl
* libgcrypt20
* libmagic-mgc
* libmagic1
* libpam-systemd
* libperl5.24
* libprocps6
* libraspberrypi-bin
* libraspberrypi-dev
* libraspberrypi-doc
* libraspberrypi0
* libsystemd0
* libudev1
* libwbclient0
* openssh-client
* openssh-server
* openssh-sftp-server
* patch
* perl
* perl-base
* perl-modules-5.24
* pi-bluetooth
* procps
* raspberrypi-bootloader
* raspberrypi-kernel
* raspi-config
* samba-common
* shared-mime-info
* ssh
* systemd
* systemd-sysv
* tzdata
* udev
* wget

Does someone have any idea which of these packages might be causing this issue? Is this maybe a known kernel issue or sth. similar?

Best regards

Stefan

Try this to force the nice to 100mbit and report back.

Sudo apt install ethtool

/sbin/ethtool -s eth0 speed 100 duplex full autoneg on

If that works you need to run the command at boot as it isn't persistent. Let me know if u need help running it on boot and I'll copy my device file.

Can you explain in which way forcing the NIC to 100MBit/s will solve my issue with the USB DVB-S receivers?

There are known issues with gigabit adaptor which shares the USB bus. I had similar issues with IPTV streams and it helped a lot. Worth a shot anyway. Only takes a minute to test.
