Just interesting, how hostname "acer" related to "HP Compaq 6715s"? It's 
just a coincidence? :)

I have Acer TM6292 notebook with bge LAN. And my bge works fine after 
resume. The only specific of my notebook is that it's BIOS does not 
allocate resources for PCIe bridges. FreeBSD also unable to do it, so 
now I have to use dirty hack to initialize them. I think I have seen 
alike bge messages (but without reboot) when that hack was working only 
on boot, but not restoring PCIe bridges state on resume.

Core is good. May be it can be debugged?
