Regarding PCI-E error display in FreeBSD

Does FreeBSD has provision to display PCI-E errors. 

we are observing a FreeBSD OS hang while performing a phy break of an
expander during IOs on the drives attached to the expander.

The same test when run under linux we could see Linux OS popping up PCIe
related error messages which was detected through their AER module.

Please help me in understanding if there are any such modules in FreeBSD
through which PCIe related error message can be viewed.
