[Asterisk-Dev] Digium TDM22B with ASUS Pundit-R barebone

[Jacky]

Hi, all

I run Gentoo OS at ASUS Pundit-R barebone, it seems no problem under OS level.
but When I load wctdm module for Digium TDM22B, and run sipp to benchmark.
It seems the system lock or hang.

I find there are very huge "TDM PCI Master abort" error in /var/log/messages
it is generated by wctdm.c


  if (ints & 0x10) {
           /* Stop DMA, wait for watchdog */
           printk("TDM PCI Master abort\n"); 
           wctdm_stop_dma(wc);

How can I solve this abort problem?
