well you hit the nail right on the head there.
I've just been running the 2.5.42-mm2 kernel except for the dcache_rcu
patch for a full hour, and I was unable to reproduce the hangs that I
saw with the full -mm2 patch installed. Did two full kernel builds
while reading some mail and doing other stuff - no problems what so
ever.
Just to be sure, I re-applied the dcache_rcu patch, rebuilt the
kernel, booted with the kernel containing dcache_rcu patch,
and the system died within a few minutes.
So it is definitely something in the dcache_rcu patch that does it.
