VMWare recommends contacting the hardware manufacturer for updated BIOS or possible workarounds.
Possible workaround can include replacing CPU socket which owns faulty VTD unit. To help in identifying CPU socket refer to boot/vmkernel logs which gives base address of VT-d unit along with VT-d unit number.
e.g "VT-d unit 0: segment 0000 base 0xdc7fc000 ver 1:0 cap 0x8d2078c106f0466 ecap 0xf020df"
Note: A prior version of this KB article recommended that customers experiencing the problem described above work around it by configuring ESXi to disable the Intel VT-d interrupt remapper (setting boot option iovDisableIR=TRUE and rebooting). VMware ESXi 5.5 p10, 6.0 p04, 6.0 U3 and 6.5 by default disable the Intel VT-d interrupt remapper for this purpose.
VMware has recently received several reports indicating that disabling the Intel VT-d interrupt remapper is causing ESXi host failure on HPE
