Yes, in fact thanks for your query, we're looking into it now. > The Linux kernel has support for AER, see drivers/pci/pcie/aer.

I agree, if you happen to have a patch already done we'll push it upstream. Otherwise I will have to work on it when I get a chance. > I would like to know what the current position toward enabling AER in > these drivers is. Are there any objections or known obstacles?

I queried our hardware engineering and they said there was no known issues with enabling it. e1000 of course no longer supports PCIe devices so that one can be dropped. e1000e probably adds the most risk because it has our oldest PCIe hardware in it. igb and ixgbe should both work and should easily support this.
