>Description:
On a DEC Station 3000/300 - "dmesg" output below - "make release" always
crashes while building the ramdisk image for the installation floppy
with "reboot after panic: lockmgr: no context". Unfortunately a
"reboot 100" in DDB causes another panic so that the stack trace is
probably useless:
