 I cannot seem to get it to work after removing the au0828 xc5000 au8522
 modules and then modprobing the au0828 module.

To follow-up on this, it seems that if I remove and insert the au0828
enough times, it will be functional again.  Race perhaps?

It seems when it's inserted and doesn't work, the following is logged in
the kernel message buffer:

xc5000: Device not found at addr 0x61 (0x)

and when it's inserted successfully:

xc5000: Successfully identified at address 0x61
xc5000: Firmware has not been loaded previously

It also seems that the module will become non-functional just as if I
had removed and inserted it, all on it's own without any removal insertion.

can't rmmod au0828; modprobe au0828 and have a working device

[Brian J. Murrell]

I have an HVR-950Q:

I cannot seem to get it to work after removing the au0828 xc5000 au8522
modules and then modprobing the au0828 module.

If I physically remove the device and plug it back in, it will work
fine, however using rmmod/modprobe it seems to fail on trying to read
from it.  For example:

$ gnutv -adapter 0 -out stdout -channels chans 100-3

just yields a:

Using frontend Auvitek AU8522 QAM/8VSB Frontend, type ATSC
status   | signal  | snr  | ber  | unc  | 

where the value to the right of the signal and snr toggles between
 and 0118 but no output is ever emitted.

Why would I need to use rmmod and modprobe to remove and reinstall
the driver you might ask?  To be honest I'd prefer not to have to
but with these drivers loaded suspend-to-ram hangs.  This never used
to be the case on previous (2.6.32ish) kernels but now with the 3.2
kernels that I have been using it is the case.

So in fact, if the hanging-on-suspend problem could be fixed, this
other issue with a failing device after rmmod/modprobe would be moot.

Any ideas on either problem?

Cheers,
