I had to disable my E cores and I turned soft updates back on.  I'll have to 
get my other drive with CURRENT setup so I can try that out to see if this is 
just a 13.1 issue.

The problems are random but the interesting part is when it happens it's 
repeatable.  In this case installing packages using conda caused the initial 
crash then an rm -rf of the env dir caused this error:

g_vfs_done():gpt/data0[READ(offset=207974961480630272, length=32768)]error = 6
UFS: forcibly unmounting /dev/gpt/data0 from /mnt/devel

After the 2nd crash in X is when I saw the above error from the commandline.  
When I booted back into multiuser I did get a savecore:

panic: vm_fault_lookup: fault on nofault entry, addr: 0xfffffe0083841000

This one was new the rest were either 'ffs_blkfree_cg: freeing free block' or 
'page fault'.  


Amar.
