[Asterisk-Users] TDM400P hardware problems

Some of the "REV H" boards have been problematic.  If you have one of these
and you are having trouble, you should contact Digium.

These cards have always been problematic for me.  

Make sure the cards aren't sharing interrupts. 
Always make sure you use filtered power (UPS or a good powerbar).  
You might get lucky and find that re-seating the card or changing PCI slots
helps. Failing that, try using a completely different PC.  

We've found a system from Shuttle (all intel components) that tends to keep
the card very stable - so we standardize on it when building Asterisk boxes.

You'll probably find that stopping * and re-loading the card module
(wcfxs) will correct the issue (temporarily).  Aside from that, make sure
your customers know how to hit ctrl-alt-del on the pbx...
