Partition problem

Hello, all.

I do not believe that someone will look into the following description of 
theproblem, but may be this is in the area of known problems in 4.7 and I 
simply waste my time...:-)

I have two tasks working on the same partition - taking buffers and returning 
back. Buffers are all of the same size.

When the tasks are working sequentially, everything is OK.
But when I make them to work in parallel (one may interrupt the other), very 
quickly I receive the exception on rtems_partition_get_buffer, which shows me 
(after diving into the rtems code) that the element 
the_partition->Memory.first has garbage value (all the rest of the structure 
looks normal).

I tried to catch this with my bdm debugger, but after one full day I gave up - 
too complex to catch this at the moment of corruption as this value changes 
all the time.

I shall be very very thankful to everybody who knows something which can help
