panda siren on ignition off

[sshane]

Not sure if fully reliable, but this happened for me after disengaging and quickly turning vehicle off at the end of this route: https://connect.comma.ai/b9d015f8ff659e1e/0000043a--98baf2b862

from greg:

RAM device beeping when I shut the vehicle off at the end of this route and when I turned the vehicle back on it also beeped. I think it was the panda alert beeping.

This has been happening for quite a while for me also. I never made an issue due to not being sure of how to reproduce it.

What are your dongle IDs?

I have this issue as well sometimes, albeit on SunnyPilot 0.9.7.1 (I know, not stock).

I see this when restarting op/device while car still on (and possibly engaged).

That's expected.

I see this spammed when the car turned off, the can packet dropped out, and it reports 500+ can core resets, so perhaps the siren was valid here?

@adeebshihadeh Want me to look into this further?

That's just because the ECUs on the bus go offline before we finish TX'ing all our msgs; it's fine that the TX fails. Those are some pretty low level logs.

Yes
