How artifcact.ci.freebsd.org's head/r356187/powerpc/powerpc/ fails to boot a PowerMac G5: lock "tfo_ccache_bucket" ... already initialized

[Mark Millard]

Using materials from:

https://artifact.ci.freebsd.org/snapshot/head/r356187/powerpc/powerpc/

put on an SSD, I tried booting a PowerMac G5
with the 32-bit system (historically supported).
Below is typed in from a screen image that
shows a panic.
