Just tried the 2.6.27-3 kernel with 8.10 Alpha5 64bit (updates from this morining) on a Intel DG945GCLF Board & network problems are back (was working most times with 2.6.26-5, but not on every boot). Network manager says network is connected ok, ifconfig shows its got an IP but i get "Destination Host Unreachable" when i ping my router. Have tried bringing up interface manually & get the same symtons.

I get this in the messages file...
