Just had this panic on -current/amd64, but it doesn't make for much of a bug report:
Crash version 10.99.2, image version 10.99.2. crash: _kvm_kvatop(0) Kernel compiled without options LOCKDEBUG. System panicked: kernel diagnostic assertion "uvm_pagelookup(&aobj->u_obj, (UAO_SWHASH_ELT_PAGEIDX_BASE(elt) + j) << PAGE_SHIFT) == NULL" failed: file "../../../../uvm/uvm_aobj.c", line 1364 Backtrace from time of crash is available. crash> bt end() at 0 crash: _kvm_kvatop(ffffb610cec18aa8) crash: kvm_read(0xffffb610cec18aa8, 8): could not read PT level 3 entry: Invalid argument I'll try running with LOCKDEBUG for a bit...
