Hi,

A bhyve VM I run had this:

pid 79784 (bhyve), uid 0: exited on signal 6 (core dumped)

and the only thing on the console was this:

ahcich0: Timeout on slot 27 port 0
ahcich0: is 00000000 cs 00000000 ss ffffffff rs ffffffff tfd 50 serr 00000000 cmd 1000c017

(ada0:ahcich0:0:0:0): CAM status: Command timeout
(ada0:ahcich0:0:0:0): Retrying command
Assertion failed: (aior != NULL), function ahci_handle_dma, file /usr/src/usr.sbin/bhyve/pci_ahci.c, line 493.

I guess the disks were just too busy?
