2.6.29-rc4-rt2 spuriously locks up after 30 min to 2 h. First the network dies (no ping either to or from), later it takes the whole machine down as file I/O is blocked too. I have also observed this on a no-RT patched 2.6.29-rc4, though need to get a clean gpl trace there first. (Note that this -rt dump has not tainted.)
