Hi.

I've just built myself a media center and installed CentOS 6.2, with the intention of installing MythTV over that.

When I compile the latest kernel drivers (v120212 or v111118 have been tried) for my TBS 6981, I get a kernel panic on the reboot following the install. The kernel is 2.6.32-220.el6.x86_64.

There rather a lot of information following the reboot, and I am unable to capture it to send through easily, however, some of the information I see is:

This is around the tenth time I've re-installed making sure I have the kernel-headers and kernel-devel packages correct, updating the kernel first, not updating, etc. I keep getting the same response each time I retry the compile.

The whole point of going for CentOS was for the stability aspect (not wanting the frequent updates from Fedora), and I'm reluctant to head for Ubuntu/Knoppix, etc.

Basic system specs are:
Gigabyte GA-870-USB3
AMD Phenom II x4 960T @ 3000MHz
4x 2GB Crucial Ballistix 1333MHz
Zotec GT 430 nVidia Passive


Any suggestions welcomed.

hi, have you confirmed your 6981 card is working? i'm asking, because there is not much from the log pasted before 'tbsfe_attach' and if that's what crashes it could mean your board is faulty and that's way the driver can't attach. so, as a first step towards resolving the issue i would suggest just for test to install Ubuntu 11.10 and the drivers and confirm there if your 6981 board hardware is fine, because if there is such crash then we can exclude any driver problems and it would mean your 6981 card is faulty and it needs to be replaced under the warranty with new board.

Thanks for the fast reply cody (and the email)...

I've not tried installing another OS just yet, but that is certainly something I can try. I'd purchased the card from Amazon a while back (~ May 2011), but hadn't got around to installing it until now. I will download Ubuntu 11.10 tomorrow (in work!) and give that a go, but it'll most likely be early next week now as I am away this weekend.

Cheers for now.

Hi Cody.

After 3 hours of installing Ubuntu 11.10, downloading kernel sources and compiling I have the following results...
