At the time of the panic I used drm-kmod-g20190710, which was built at OS update time.

Following the panic I installed drm-devel-kmod instead …

FWIW I see the same strings (with a different version of FreeBSD) at https://github.com/FreeBSDDesktop/kms-drm/issues/130#issuecomment-460614356

From https://gitter.im/FreeBSDDesktop/Lobby/archives/2020/09/20?at=5f67c00dc1d1a53705b5932d yesterday evening:

… good news: in recent months, both drm-devel-kmod and drm-current-kmod seem far less likely to panic for me with 'Thames [Radeon HD 7550M/7570M/7650M]'. So I'd like to close both of these, unless anyone can think of a good reason to keep either one open:

  • FreeBSDDesktop/kms-drm#158 …
  • FreeBSDDesktop/kms-drm#159 for drm-current-kmod and drm-devel-kmod.

…

No comparable panic in recent months.
