Dear listmembers,
the change did not change anything apparently - what had had to be expected, as the negative numbers presented for the size of partition three must be caused by some printfs' into /proc/partitions or alike.
If someone would kindly guide me as where to look for this issue I am willing to test - using unsigned should increase the limit by a factor of two - not too much, but neither too bad.
Take care
Dieter Jurzitza
