i got this same error/problem on the latest model of the pundit's with the same digium card<br><br>on inspection of the logs (using dmesg on ubuntu) all i saw was 'TDM Master PCI abort' spewed out repeatedly. on inspection using top, i saw it was mostly the log daemons eating cpu cycles tryin to keep pace writing the error messages to the log files.
<br><br>so, i opened up the wctdm.c file in the zaptel source (at time of writing using stable 1.2) and commented out the line that printsthis message to the logs<br><br>so far, no excessive cpu usage, although i cant really report on the cards behaviour since the lines its connected to are messed up somewhat (we're waiting for a BT engineer to come out and sort the mess they created 10 or so years ago)
<br><br>usuful info ont he tiger chip used on the digium cards (from google) <br><br><a href="http://66.102.9.104/search?q=cache:T8oGn80H_MkJ:www.tjnet.com/software/download/data_sheets/Tiger320_data_sheet.pdf+tDM+PCI+Master+abort&hl=en">

to a newer board fixed it for me. I don't know if anyone has a more
