    SubjectRe: sky2 hangs
    I can reproduce the problem now (on mac mini). Interestingly it seems to whack
    the whole ethernet switch when it happens.

    It is not an MSI or IRQ problem. It is a phy problem (see below).

    If you do:
    ethtool -r eth0
    it cause a PHY reset (renegotiation) and clears the problem.
