Wondering how this can be explained: Just after using Disk Utility Restore to put an image of an EFI Apple Service Diagnostic on a flash drive. (Btw, scanned the ASD dmg and its mounted image beforehand with Sophos, and it gave it a clean bill of health. The restore went perfectly fine (the ASD appears as a bootable volume from the starup manager), which the DU log shows, except, curiously, the destination turned blank just after the restore finished and a few seconds later it KPed.
Wonder if Sophos InterCheck got into the middle of things causing the KP? Subsequent mounting of the ASD volume does not cause a KP. This appears to have been a one off event.
The backtrace from the panic log appears to be the tipoff.

Seems to be USB kext related (DU restore to USB flash drive).

Here is the full panic log. (Never had a KP before from Sophos, and never from Little Snitch or Bresink/Hardware Monitor. In fact, this is the very first KP on this Mac in four + years).
