Hi,

Got a new one today. Copied manually:

panic: kernel diagnostic assertion (opte (& PTE_A | PTE_B)) != PTE_A pmap.c line 4029
kern_assert()
pmap_sync_pv()
pmap_pp_remove()
uvm_anon_dispose()
uvm_anon_freelst()
amap_wipeout()
uvmspace_free()
exit1()
sys_exit()
syscall()
stopped in (clang)

Switching back to DEBUG kernel again for now.
