problems with I2C

hello everybody,

i use a mpc860 with iic,fec and ethernet at SCC3; iic-communication normally
works fine, but sometimes
especially if there is heavy traffic on SCC3 or fec (eg. download of big files)
iic-communication stops with error

... iic-read; short, wanted 32 got 1 ...

also the data seems to be corrupt

it looks like receive buffer descriptor is not the same as before ... ?

has anybody else had these problems or some ideas ?

thx matthias
