Can you please try this change, whether it helps in your case ?

In mantis_dvb.c

line #251

if (!lnbp21_attach(mantis->fe, &mantis->adapter, 0, 0)) {

change it to

if (!lnbp21_attach(mantis->fe, &mantis->adapter, 0x80, 0x40)) {

and see whether it helps in improving your current limited situation.
according to the specification it should yield 500 - 650mA

A word of caution, make sure that the auxilliary power connector is
connected. Current drawn will be a bit much higher in this case,
additionally Static Current Limiting is used, hence additional dissipation,
which means more current drawn which might overload the PCI bus, hence
  it would be nice to use the auxilliary power connector.
