Umm.. Looks like chip registers is normal, but TX/RX interrupt doesn't
happen. (BTW, there isn't rtl8139_open on debuginfo.txt. Was it already
scrolled?)

The following patch (incremental patch) is some part reverts to
2.6.2. Is behavior changed?

Please try 8139too-revert01.patch, and 8139too-revert02.patch.
