#69906 — Bug#985687: linux-image-5.9.0-0.bpo.5-armmp: Set CONFIG_CAN_J1939=m

Package: src:linux
Version: 5.9.15-1~bpo10+1
Severity: normal

Dear Maintainer,

Please consider setting kernel option "CONFIG_CAN_J1939=m" for at least
buster-backports armmp. Without this setting the CAN J1939 protocol can
not be easily used.

Regards
Andrew

Yikes, how did I miss that? I guess it was too late in the night ...

We tried 5.10.13-1 a few weeks back, but it had a kernel panic on
boot. Without time to debug, we just reverted to a working 5.9.15-1. I
see a promising bug fix in 5.10.13-1 changelog. We'll try again.

Thanks for the help and apologizes for the noise.

Regards
Andrew
