The output of `lspci -vvvs 01:00.0` is attached. Interestingly, the command
generates an error somewhere in the middle of the output:
pcilib: sysfs_read_vpd: read failed: Input/output error
The corresponding `dmesg` output is:
[ 2587.922711] vfio-pci 0000:01:00.0: invalid short VPD tag 00 at offset 1
I blacklisted the `mpt3sas` driver and assign the device directly to VFIO:
$ cat /etc/modprobe.d/vfio.conf
blacklist mpt3sas
options vfio-pci ids=1000:0072
Best,
Damon
