Public bug reported:
I think this issue started happening with a late 5.x kernel and has
persisted through 6.x
# cat < /dev/vbi0
cat: -: Cannot allocate memory
I should be getting data from the vbi0 device.
# lsb_release -rd
Description: Ubuntu 22.04.3 LTS
Release: 22.04
I'm not sure if this is a bt878 bug but seems a good place to start.
Happy to provide more details as requested.
