<br>Hi,<br><br>update on the issue: the problem I reported initially has been solved and had very little to do with dahdi or the digium board itself. <br><br>The motherboard in the test system uses an Intel ICH7 SATA controller which provides some sort of IDE emulation even for SATA HDs. The Linux generic IDE driver was grabbing the device early, and the disk was being accessed with DMA disabled (and hdparm would refuse to turn it on due to driver limitations). After disabling the generic IDE driver and having the controller attached to the proper ata_piix kernel driver, te205p/dahdi begun to work properly with our ISUP/mtp3/mtp2 tests, with negligible error rate.<br>
<br>Thanks for the help and for the tips on ELAST/event queue behavior,<br><br>-- Felipe Bergo<br>Labcom Sistemas, Campinas, SP, Brazil.<br><br><br>
