Tvheadend

I have some kind of similar problem. Running Ubuntu 12.04. What does your log say when you get the kernel panic?

Hi

I did never find the couse for this. But i ha e some teorys

There is a bug in the newest debian kernel, related with apic
Follow boot closly and you see some apic error. This can be disabled in grub with option noapic
But this is a hard error. Kernel have trouble with bios api. You need to have latest bios on your server.

The other probable couse is the firmware to the dvb cards. Its so crapy this hauppage shit.. :)
I have orderd a new tbs 4 tuner cards similar to what adam use.

I did a freesh install of debian when the new tvheadend was released with new framwork, sins that time i have had no issues.

My server was also cloged up with some dust. I dont have overpressurized server rom ready yet.
I took out the dvb cards and refitted them.

After i did this i have had no issues.. kernel panic is not coused by tvheadend but hardware or driver issues related to dvb cards. What drivers did you use? And how did you install it?

Memory can also couse this issues. I bought new ram for my server just to eliminate that issue. ECC was triggered a couple of times with old ram. This indicates its lived its life. ECC ram is not something that is commonly found in home computers.

At the moment I use the standard firmware that comes with the package "linux-firmware" (from standard Ubuntu 12.04 repositories). dmesg shows:

cx24116_load_firmware: FW version 1.26.90.0

But this machine is a crappy old Dell Optiplex 745, so it could perhaps be many reasons. I've used this firmware before without problems. That was on another machine and older software (Ubuntu and tvheadend).

Also see a lot of messages like these in dmesg:

[45312.097803] cx88[0]: irq mpeg  [0x80000] pci_abort*
[45312.097809] cx88[0]/2-mpeg: general errors: 0x00080000

But problem is the real crash is not something that is consistent. It is hard to reproduce the problem when I want.

FWIW I believe I have one of these cards. (It's called the same thing but may differ in detail. lscpi gives:

09:01.0 Multimedia video controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
09:01.1 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder [Audio Port] (rev 05)
09:01.2 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder [MPEG Port] (rev 05)
09:01.4 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder [IR Port] (rev 05)

I'm not suffering your problems. Currently on Ubuntu 13.10, but have also used it since 12.04, possibly even earlier.

FWIW I believe the cx24116 firmware in use is the dvb-fe-cx24116.fw which is actually from linux-firmware-nonfree. Maybe that makes a difference. However, my dmesg output for load_firmware is identical to yours. (Actually from rotated syslog; I just realised, because of looking for this, that the kernel's dumping tons of stack traces to my logs because, i think, of the fglrx driver, so dmesg from boot had scrolled out of existence, but that's another story):

I notice at the end of that I am getting the same thing you reported... but only that once, in all my syslogs still in rotation, during the last boot; not even in a couple of other earlier boots still in logrotate. Not all the time, not happening a lot, and the one time it did happen, I don't believe it was associated with a kernel panic. (I don't remember a failed boot lately.)

Could it possibly be the problem is using three of these cards at once in the same machine?

In my machine I only have one card, but the OP had three it seemed like.

Hi

You use outdated firmware. That is the problem.
Look ant linuxtv for a updated guide how to install the correct firware.
Do not use apt. Install it from scratch.

I will upload firmware latertoday and a guide how to install.

It doesn't say in the wiki of linuxtv that 1.26.90.0 is "broken", and updated firmware isn't necessary more "correct". I'm missing some kind of information stating that 1.26.90.0 is broken in Ubuntu 12.04. That would help, and could also be good to bring on to others so that linux-firmware-nonfree is updated with latest "correct" version of the firmware...

But, please, specific guide on installation and version you're referring to would be nice to have, so happy if you post this. It is worth the shot. As of now I'm kind of out of ideas on how to solve this.

1.26.90.0 has many firmware types...

24116 is outdated.. averything with hauppage is crap they cant do properly version controll either

88x_2_126_28225_WHQL.zip

this is the correct you should use

Note: There seems to be a more recent version of this firmware:

There´s a forum article describing how to extract the firmware: [1] --- see post #3. The download link to get the driver now seems to be [2]. Download it with:

wget http://www.wintvcd.co.uk/drivers/88x_2_126_28225_WHQL.zip

Extract the firmware and put it in the firmware directory :
unzip -jo 88x_2_126_28225_WHQL.zip Driver88/hcw88bda.sys

sudo dd if=hcw88bda.sys of=/lib/firmware/dvb-fe-cx24116-1.26.90.0.fw bs=1 skip=105768 count=32290
sudo ln -s /lib/firmware/dvb-fe-cx24116-1.26.90.0.fw /lib/firmware/dvb-fe-cx24116.fw

For verification of hcw88bda.sys in this version of the driver:

md5sum -b hcw88bda.sys
3f685a2ca6d1dae35b10c06f3a538d82 *hcw88bda.sys

The firmware will be reported as

sudo dmesg|grep cx
cx24116_load_firmware: FW version 1.26.90.0

I'm giving it a shot. Rebooted with new "version" now.

Let us know how it goes

Didn't seem to change anything. I can see some messages like this in syslog before it hangs:

Same problem here (Nova S2 + Gigabyte Mobo). The system ran without any error for some years (Debian Squeeze). After upgrading to wheezy, it freezes every 3-5 days or so :-(

BIOS and cx24116-firmware are the newest versions ...

Hi

Iam still having problems with my dell poweredge 2850 with 3 of those cards, i use wheezy on it with manualy installed drivers, i havent tried the apt firmware yet.
but in general it get unstable, one card will fail to decode or some other weird shit happens after around 4-5 days. i think its related to debian, firmware or something.

the image cache function for icons does not work in debian either
