Yeah, I knew I forgot to send the contents of /proc/iomem. I'll include them below.
I'll also include the lspci output for after. The one I included in the last mail was for 'before'.

Hm, that is a good question. ;) The particular device I was testing with was an infiniband device, and I have never actually pushed any traffic over it; just used it to reproduce the error.
I can try and hook the card up to something and push traffic over it, but that will have to wait until Monday. Maybe Justin (cc'ed) knows, since he was the one who first reported this to me.
Lots of data follows. The revert output I'm including is with my complex revert patch. I'll try the 2-liner next and respond in a separate mail.
(a) mainline /proc/iomem before hotplug (b) mainline /proc/iomem after successful hot-remove (c) mainline /proc/iomem after hot-add + BAR error printk (d) mainline lspci -vv after operation (c) (e) revert /proc/iomem before hotplug (f) revert /proc/iomem after successful hot-remove (g) revert /proc/iomem after successful hot-add
Thanks.
