[asterisk-users] Moh stuttering

[Boyd Goodin]

   hello Jason.


     It is using DMA. When the stutter happens it happens across all inbound
or sip lines at the exact same time.  I thought it might be the IDE drive
but I have noticed it happening with no disk activity at all.

have you verified that dma is enabled on all of your harddisks?

hdparm -d /dev/xxx
