I just upgraded to kernel 2.6.20.1 and my HD-5500 now can't seem to tune to any digital channels. The analog channels are working fine so I know the cable is connected.
MythTV's autoscanning and dtvscan both can't find any of the unencrypted QAM-256 channels that I could tune with the 2.6.18.6 drivers.
I don't know if it's related, but I'm also now having to manually modprobe the lgdt330x driver whereas it was automatically being loaded under 2.6.18.6.
Here are the load messages:
| Code: | cx2388x cx88-mpeg Driver Manager version 0.0.6 loaded

And after manually loading lgdt330x and cx88-dvb:

Help me xyzzy, you're my only hope!
Thanks,

| If you just modprobe cx88-dvb after booting, and not lgdt330x, does cx88-dvb load? lgdt330x should be automatically loaded when cx88-dvb is. |

| Nope. I was getting errors until I started manually loading lgdt330x before cx88-dvb. |

| What errors do you get when you try to load cx88-dvb before lgdt330x? And what version of module-init-tools do you have? /sbin/modprobe -V to check. |

In the ringbuffer:
| Code: | cx2388x cx88-mpeg Driver Manager version 0.0.6 loaded
cx88[0]/2: cx2388x 8802 Driver Manager
ACPI: PCI Interrupt 0000:07:04.2[A] -> GSI 17 (level, low) -> IRQ 17

cx2388x dvb driver version 0.0.6 loaded
cx8802_register_driver() ->registering driver type=dvb access=shared

cx88[0]: frontend initialization failed
cx8802_dvb_probe dvb_register failed err = -1
cx8802_register_driver() ->probe failed err = -1 |
These errors go away if I manually modprobe lgdt330x. And at the console:
| Code: | | FATAL: Error inserting cx88_dvb (/lib/modules/2.6.20.1smp-beryl-05/kernel/drivers/media/video/cx88/cx88-dvb.ko): No such device |
This is a CentOS 4.4 x86_64 host.
| Code: | $modprobe -V
module-init-tools version 3.1-pre5
$rpm -q module-init-tools
module-init-tools-3.1-0.pre5.3.2 |
Thanks for your help with this xyzzy. I appreciate it.

There is the problem and the cause. A new method of dynamicly loading needed drivers went into 2.6.19, but it needs module-init-tools 3.2. There is a bug in 3.1 (which is a few years old) that keeps it from working. The command modprobe symbol:lgdt330x_attach should load the lgdt330x driver, but it won't work if you try it until you upgrade module-init-tools. |

I guess my problem is trying to get this to work on a stodgy old distro like RHEL. I'll try to hunt down the correct module-init-tools.
Thanks again for looking at this. I really appreciate it.

Update:
I downloaded the Fedora Core 5 source RPM module-init-tools-3.2.2-0.FC5.3.src.rpm and rebuilt it for my system. After updating with the resulting binary RPM. I updated my /etc/rc.d/rc.local with
| Code: | modprobe symbol:lgdt330x_attach
modprobe cx88-dvb
|
and the MythTV channel scanner now finds the missing channels.
Many thanks. |
