Yes, I've read then.

They say it can be caused by interruptions.

I tried asterisk on kernels 2.4.29 and on 2.6.10 and I got the same errors.


At this moment, I am running the latest version available on cvs on kernel
2.6.10 and I took off all other cards (4 FXO - Intel Ambient 3200) and still
get the errors.

The TE405P card is not loosing interruptions any more...


Have a see...

I contacted Digium Instalation Support and I am waiting for their response.

They say it can be caused by interruptions.

Did you confirm you are not running graphics? (X, frame buffer, etc).
Did you confirm you have unmasked IDE interrupts (-u1 to haparm)?
