This does not seem to work with OpenMediaVault 0.5

My HDHomerun (HDHDR3-EU, dual tuner) works fine for a little while after starting dvbhomerun-utils, and I can watch TV through tvheadend. However, after a while (anywhere from a few minutes to half an hour or so), the signal just seems to drop. Switching to another channel doesn't work, and tvheadend reports "no input detected". The moment this happens is clearly visible when running femon:

status SCVYL | signal  94% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK
status SCVYL | signal  94% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK
status SCVYL | signal  94% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK
status S     | signal   0% | snr   0% | ber 0 | unc 0 |
status S     | signal   0% | snr   0% | ber 0 | unc 0 |
status       | signal   0% | snr   0% | ber 0 | unc 0 |
status S     | signal   0% | snr   0% | ber 0 | unc 0 |

However, even after this, the QuickTV application for Windows provided by SolliconDust has no problem tuning into a channel, and will happily show me the program.

Also, restarting dvbhdhomerun-utils immediately resolves the problem, as shown again by femon:

status       | signal   0% | snr   0% | ber 0 | unc 0 |
status       | signal   0% | snr   0% | ber 0 | unc 0 |
status     L | signal  11% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK
status SCVYL | signal  94% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK
status SCVYL | signal  94% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK
status SCVYL | signal  94% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK

The dvbhdhomrun stderr log is empty, and the stdout log doesn't seem to have a telltale entry around the time the signal "drops".

Another weird thing I see is this kind of output from femon:

status SCVYL | signal   0% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK
status       | signal   0% | snr   0% | ber 0 | unc 0 |
status SCVYL | signal   0% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK
status       | signal   0% | snr   0% | ber 0 | unc 0 |
status SCVYL | signal   0% | snr   0% | ber 0 | unc 0 | FE_HAS_LOCK
status       | signal   0% | snr   0% | ber 0 | unc 0 |

Notice the alternating "FE_HAS_LOCK", and the signal at 0%. In this state, I can still watch TV without any problems. Not sure if this is related, but I'm just putting it out there under the premise "more data is better", when investigating a bug.

I realize this may not be the most appropriate place for this, but this is kind of my last-ditch attempt to figure this out, as I am out of tricks. I know you are not the original author of this driver, but it looks like the original project is kind of dead.

If there is anything I can to help debugging this issue (more/other logging), I'd be happy to do so.

Hi. I've used your software 2 or 3 years for my, now old, HDTC-2US to schedule recordings of ATSC programs with kaffeine, thanks. Last year, newer kernels in Mageia, ROSA, OpenMandriva, and any distro I tried all failed the kernel module build in what looks to me the same way.

The latest I have made to work is 4.6.7-nrj-desktop-1rosa-x86_64 on ROSA.
4.9.30-desktop-1.mga6 on my installation of MGA6 RC fails with the same message, below, as all the failures. I installed 4.4.68-tmb-desktop-1.mga5 along with the kernel-devel package and it works. That makes me believe it's something in the kernel, as none of the other software is changed.

I followed some advice here to add -wno-error=incompatible-pointer-types and that failed differently. Maybe I should attach that output as a text file, as there's more to it, in case it is of interest. Thanks.

I'm a real novice so I need some help on an Ubuntu 20.04 install. I figured out how to add all the dependencies that at first were not present. The build shows two problems:

The second issue is:

I tried going into the file in question and just adding "_v3" but that just led to a different error.

I have no idea how to address these problems. Any help would be appreciated.

Hi

Thanks for this, will you do an update to make it work on current Debian Sid?

I tried and get an error, where it can't modprobe dvb_hdhomerun.

After getting your code to compile and load into my computer I noticed the dmesg had some errors in it. Seems to be a bad pointer somewhere in your code. I've attached my dmesg output, hopefully you know how to decipher it.

I did see that there is a failure early on

[   16.531894] DVB: registering new adapter (HDHomeRun)
[   16.531896] vmalloc: allocation failure: 18446743833813787648 bytes
[   16.531897] userhdhomerun: page allocation failure: order:0, mode:0xd2

I tried increasing my vmalloc in grub (not sure if it worked), but I didn't increase it by 18,446,743 terabytes either.

dmesg.txt

System Info:
Running in ESXi system
Fresh install of Ubuntu 15.04 x64

Steps to reproduce:

1. Install Ubuntu
2. Install compile tools
3. Run dpkg-buildinstall -i

Tried your build instructions, got compile error. Looks non-obvious to fix.
