Hi John,

still no solution?

Put in /etc/modprobe.conf
options saa7134 card=118,118 tuner=54,54 gbuffers=32 latency=64
Do a "depmod -a"

Power down, remove all power and the md7134,
especially if not in the original blue PCI slot.

Are you able to come up now?

If so, "modprobe -vr saa7134-dvb tuner tda827x" and
"modprobe -v saa7134" several times.

Have a look in "dmesg" if the eeprom readout is always the same.

There seems to be a potential issue, if multiple cards with eeprom
detection are in the same machine, the readout is sometimes corrupted.

This must not be related to your issue, but please test.

Anyway, the card is unnecessarily in the Philips' reference boards
eeprom detection if auto detected.

I'll provide a patch to remove it from there.

Cheers,
Hermann
