Product: Base System
Version: 11.4-RELEASE

Hi All,
The FreeBSD 11.4 vanilla VM downloaded from freebsd.org is crashing when doing
passthrough of Intel NIC
"Ethernet Controller X710 for 10GbE SFP+" after a couple of reboots.
In the ESXi kernel logs seeing this message
Code:
cpu10:2235436)IntrCookie: 1565: Unable to allocate 128 cookies: Out of

The issue is not seen 10.* freebsd VM. Looks like there is some issue with
pci_alloc and free functions. First of all why ESX allocating 128 interrupts
for one MSIX interrupt. And again after some reboots all the available
interrupts are exhausted.
regards,
mak
