[SOLVED] Since PVE7 the CT with an DVBcard hasen't access anymore

[fireon]

Hello all,

pve-manager/7.0-8/b1dbf562 (running kernel: 5.11.22-1-pve)

i have here on LXC with an DVBcard. The CT is starting but no longer has authorization to the device. This Message is from inside the CT:

[4148063] ERROR (dvbdevice.c,1903): /dev/dvb/adapter0/frontend0: Die Operation ist nicht erlaubt

On the host at the same time i get this error message:

segfault at 0 ip 0000000000000000 sp 00007f7dd3084de8 error 14 in vdr[560841ca3000+90000]
Code: Unable to access opcode bytes at RIP 0xffffffffffffffd6

I guess after the error message it doesn't look so good....

Here is my ctconfig:

memory: 4096

Have you tried replacing all cgroup occurrences with cgroup2? That seemed to fix it for other people here.
