Can you tell me how I can verify this? I've always built my kernels
with make buildkernel (that is, I have not used quickkernel).

I don't have a leaf account as yet. But the new issue looks very
similar to issue 2044 [*]. The submitter of issue 2044 has uploaded
the kernel/dump files (kern.18, vmcore.18) to ~mh/crash.
