10.99.7 panic: defibrillate

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I just got a new panic in 10.99.7 after running a pbulk for less than
a day (after updating from 10.99.5, which was stable for weeks).

OCR'd from screenshot and manually corrected:

Sorry, no crash dump available.

Any ideas what this one is about?
