asterisk users - Jun 2005 - HDLC abort 6 error

I've read as much as I can on this error and still can't seem to figure
out what's causing this error:

Jun 23 20:54:58 NOTICE[7483]: chan_zap.c:7395 pri_dchannel: PRI got event:
HDLC Abort (6) on Primary D-channel of span 1
Jun 23 20:55:03 NOTICE[7483]: chan_zap.c:7395 pri_dchannel: PRI got event:
HDLC Abort (6) on Primary D-channel of span 1
Jun 23 20:55:03 NOTICE[7483]: chan_zap.c:7395 pri_dchannel: PRI got event:
HDLC Abort (6) on Primary D-channel of span 1


If I restart my entire machine it will work and assign the D channel
correctly , but after a few minutes it then starts producing this error. 
I have changed the second number in my /etc/zaptel.conf span='s line to a
0, as instructed by Digium and still have the same issue.  I'm running
Gentoo with plain old 2.6 vanilla sources.  My Te110p card is the only
thing on it's irq and when I run a zttest I get all 100% - 99.975586
(lowest).  I'm really at a loss here.  My card has a solid green light. 
It's a Bellsouth PRI 12 -bchannel and 1 dchannel new install.  Any ideas,
please help.  Thanks.

Hi,

a common reason for HDLC aborts is interrupt latency/jitter. Most likely
when you are sharing an IRQ, are not using DMA mode for IDE disks or
your IDE controller is disableing all IRQs while it is servicing his
own. 
If you have an IDE system please check:

hdparm -d /dev/hdX
hdparm -u /dev/hdX

Welcome to the worls of software hdlc. :-)

best regards
