Package: src:linux Version: 4.19.28-2 Severity: normal Hi all,
I'm using Odroid C2 as a mini-PC as DVB-C receiver. I've connected 6x TechnoTrend TVStick CT2-4400 and 2x TechnoTrend TT-connect CT2-4650. With 6 devices is working fine, when I'm starting the 7th DVB after a while or instant I'm receiving a module Opps. As streaming software I'm using dvblast. Seems that this issue is also present in previous kernels. I'm using external power supply for 2x USB 3.0 Hubs where DVB-C devices are connected and which is powering those devices. Kind regards, Adrian -- Package-specific info: ** Version: Linux version 4.19.0-4-arm64 (debian-kernel@lists.debian.org) (gcc version 8.3.0 (Debian 8.3.0-2)) #1 SMP Debian 4.19.28-2 (2019-03-15) ** Command line: BOOT_IMAGE=/boot/vmlinuz-4.19.0-4-arm64 root=UUID=28fed50d-70fa-46ab-921f-12e065fc842e ro max_freq=1296 quiet ** Tainted: D (128) * Kernel has oopsed before. ** Kernel log: [ 43.809682] IPv6: ADDRCONF(NETDEV_UP): eth0.4091: link is not ready [ 43.930304] systemd[1]: Started Raise network interfaces.
