Public bug reported:
Thunderbolt device causes system crash on first hotplug in Ubuntu 24.04
(but not 22.04) – related to bolt daemon timing
=== Questions ===
1. Has there been any change in bolt activation behavior (udev / D-Bus) between
22.04 and 24.04?
2. Is there a known issue where bolt interferes with early Thunderbolt device
initialization?
3. Is there a recommended way to delay or serialize bolt interaction until
kernel initialization is complete?
4. Would adjusting udev rules or D-Bus activation be the correct direction?
=== Additional Info ===
- Platform: AMD (X870E)
- Thunderbolt device: (OWCTB3ENVPFX / OWCTB4HUB5P)
- Reproducible: 100%
=== Ubuntu Info ===
