RE: ucc_geth DPRAM alloc error, 2.6.22-rc3

You are right.  The proposed change is just an unwise suggestion.

I later overhauled and reworked the aligned allocation of rheap to
prevent it from generating internal fragment.  Patch coming soon.

This output looks buggy:

These buffer overlaps probably have a lot to do with your pings

stopping.

I would say first order of business would be to investigate what could
be generating all these overlapped allocations.  Some of these make me

think

the allocator code could be racy, like allocations are not aware of

other

"recent" or ongoing allocations.  But in any case the allocator is

broken.
