I had exactly the same problem. The faxes received was about 2 inches then
stop.

Same result all the time.

libtiff 3.5.7, 3.6.0, 3.6.1, 3.7.1 all the same.

Kernel 2.4.27
No change with 2.6.7

I suspected frame slips. But sound quality was ok. Everything was ok.
Except maybe to many interrupts on the line cards.

But when I changed my devicedriver to one that was more safe regarding
lost interrupts it worked like a charm.
