dead network on JS21 with tg3 driver after flowcontrol changes

Commit ef167e27039eeaea6d3cdd5c547b082e89840bdd ([TG3]: Fix supporting
flowctrl code) breaks networking on IBM JS21 blade servers. If I revert
this change from 2.6.26-rc2-git4, nfsroot for example will work again.
There are no packages submitted, a tcpdump on a different host sees no
broadcast messages.
Any ideas how to fix this?
What info do you need from the system?
I started with arch/powerpc/configs/ppc64_defconfig and updated CONFIG_CMDLINE
for nfsroot.
