Hi,
I am unable to get my Nebula DigiTV DVB-T card (nxt6000 frontend) working with
kernels more recent than 2.6.8.1. For example 2.6.12.5 gives the messages show
below. No frontend device is ever created.
Things work perfectly with a 2.6.8.1 kernel.
I had a bit of a play trying to debug the kernel and the problem seems to occur
around the
/* check if the demod is there */
if (nxt6000_readreg(state, OFDM_MSC_REV) != NXT6000ASICDEVICE) goto error;
lines in the nxt6000_attach function in nxt6000.c. However kernel code is far
beyond my knowledge of C :)
I have seen similar problems reported elsewhere and the solution seemed to be IRQ
related - moving the card to a different PCI slot was reported to work. However
my machine only has a single slot so I can not try that.
Any ideas?
Thanks
John
