When pmap_pinit0() allocates a page for proc0's page directory,

kernal page table may need to be extended.  But while growing the
kernel page table (pmap_growkernel()), newly allocated kernel page
table pages are entered into every process' page directory. For
proc0, the page directory is not allocated yet, and results in a
page fault.  Eventually, the machine panics with "lockmgr: not
holding exclusive lock".
