With a fresh install of 2.6.10 on a new Dell r200, after installing Digiums TE121 pri card and drivers as per http://www.voip-info.org/wiki/index.php?page=Asterisk+Linux+CentOS

the box stalls on starting udev.
I have read that it does time out and eventually start but it has been stalled for over 12 hours.

Tried acpi=off as mentioned in another forum. did not work.

the only thing that works is to take the Digium out. Then boots fine.

Any help would be appreciated.

forgot to mention that I am a NOOB

First, I would try 2.6.1.11  instead of 2.6.10
which is based on CentOS 5 not on CentOS 4

There should be _no_  need, and it could even be harmful to attempt
to install additional drivers for this card.

Drivers for the digium cards are included  with the Zaptel modules that ship with
Trixbox.

It is recommended not to install or change any software, except using the Trixbox yum repositories.

I recommend doing the clean install with the card  already installed, instead of after the fact.

Yes, I suggest a clean install, as you haven't shown enough information to indicate what you might have accidentally broke trying to add drivers for the card

I have 2 boxes 1 is the main and the other is the backup.

the backup is the fresh install nothing added

both are doing the same, stalling on starting udev.

I will try a clean install of 2.6.1.11

With the card installed I can not get past the formatting stage gets stuck at 35%.

Do you have a spare test machine that can actually boot normally with this card plugged into its PCI-Express slot?

I have used primarily TE110P and Sangoma cards,  and haven't yet had the pleasure of trying a TE121 card, but it sounds as if yours may be broken or incompatible with the board w/ the PCIE slot it's plugged into.

acpi=off is  not best in every configuration;  I have seen configurations
that  acpi=on   is best with  and are crippled with acpi=off under load.


If your system is halting during formatting; I would say that something is
very wrong with the hardware.

Do you get a kernel panic message  or any log messages at all?

When it stops, if you press the "NUM" lock key a few times, does the light toggle?

If you press Alt+F1    Alt+F2     Alt+F3   Alt+F4  Alt+F5
Alt + Right Arrow Key

do any of those key combinations change the display /
show the other views?

If   Alt+F3  changes the display, it should bring you to "console #3"
( the log messages view, where any errors would show,  if I recall correctly).

If none of these keypresses have an effect during installation, then
that would indicate the system is hardlocked (not merely that the installer
program is trying to do something that never finishes).

The problem is that the dell r200 pci slots use the same irq and Dell does not let you change that. System halts since I have to cards trying to access at the same time.
