I was digging into the SVN changelogs of sys/dev/e1000 and couldn't see any obvious changes that I should revert. Instead I went a different route and jumped to HEAD/CURRENT. I'm not seeing the mbufs leaking yet. I'll need another 24 hours to confirm. Hopefully this is a worthwhile clue. I'm a bit surprised nobody else has reported this type of behavior... maybe 10 isn't getting the amount of testing we expect? ...or maybe it's just my lonely, haunted hardware :( M> > M> M> > M> Ok, I feel safe confirming that 10.0-RCs are not stable on my hardware.

I'd like to try to assist in fixing this before 10.0-RELEASE happens or we're going to have some very angry users.

Mark, can you pleast confirm that now stable/10 no longer leaks mbufs at your setup? -- Totus tuus, Glebius.
