Bug#375995: NETDEV WATCHDOG: eth0: transmit timed out
merge 375995 358744
This is caused by a change introduced in the i915 driver in 2.6.16, and
still exists in 2.6.17. A workaround is either to blacklist i915 or to
add the "noirqdebug" kernel parameter (but the latter seems to cause
lockup when switching consoles).
