Hi,
I encountered the following panic while upgrading my packages (pkg_add
via ansible).
The machine has ddb.panic=0, so it already rebooted. Dump seems has been
correctly proceed, but savecore failed (KARL side effect ?)
savecore: reboot after panic: pool_do_get: vmmpepl free list modified:
page 0xffffff0187540000; item addr 0xffffff01875400a8; offset 0x38=0xd6adbeef
savecore: system went down at Fri Sep 28 08:07:31 2018
savecore: /bsd: No such file or directory
And now, the /dev/mem door is closed...
# savecore /var/crash
savecore: /bsd: kvm_openfiles: /dev/mem: Operation not permitted
Anyway, the dmesg buffer is still here, so I have a full backtrace (but not
'ps', sorry :-/ ).
panic: pool_do_get: vmmpepl free list modified: page 0xffffff0187540000; item
addr 0xffffff01875400a8; offset 0x38=0xd6adbeef
