panic: assertion failed: rc == DDI_SUCCESS, file: ../../common/os/devcfg.c, line: 4185
During a reboot (full, to BIOS, not "fast" reboot) on a debug kernel, on a system with nVidia graphics, I got a panic just before the restart:
syncing file systems... done rebooting... panic[cpu0]/thread=ffffff02fa136bc0: assertion failed: rc == DDI_SUCCESS, file: ../../common/os/devcfg.c, line: 4185
Here's the stack back-trace

The failure is an assert after the nVidia driver's quiesce entry point returns DDI_FAILURE. This particular assert is more annoying than helpful.
In IRC, gdamore wrote: I'd prefer to see the ASSERT turned into a cmn_err() with details about the driver that fails, and then continue on.
