Common Fixes for all cards
1. Check for shared interrupts by entering the following:
cat /proc/interrupts
and
lspci -vb
If a conflict exists, try moving the card to another PCI slot.
2. Check to see if X windows is running by entering the following:
ps aux|grep X
If X windows is running, stop the application since it may cause a
conflict with Asterisk.
3. Check to see if your IDE hard drives are running with DMA levels set.
Advance user can perform an
hdparm on your hard drive interface.
