My primary domain paniced due to FFS/softdep while; after rebooting it
i noticed one out of six guest domains having paniced as well.
This paricular one is the only one having a PCI-E device passed through,
namely one of the RAID controllers, see mpii0 in dmeg below.
mpii0 exports four identical devices with 200G each, I am using those
as RAID0 chunks.
Complete `ldomctl console' log from DDB to reboot follow; the guest is
running a snapshot from april, 20th.
