We don't have the problem anymore, but can't say for sure what fixed it. Some more things to try: - Yet another server. If possible, try a PC with 100% Intel components. We've standardized on Intel, and very rarely experience the problem anymore. - Ensure you are using filtered power (UPS or good powerbar ... make sure the cleaning lady doesn't plug her vacuum cleaner into it!) - IRQ masking with your HDD: hdparm -u1 /dev/<drive> - Someone once suggested: ---snip--- We have not experience with Digium cards. However we had similar problems when installing legacy pbx. The problem: local ground. One easy way to test the local ground is with a voltmeter measure the voltage between the CO tip wire (in open loop state) and local ground. This must be less than 2 VDC and must be stable (not oscillations). Correcting the local ground all problems were fixed. ---snip--- - Perhaps it's environmental? Sounds stupid, but try running your server in a different room, or on a different rack. I guessing these cards are very sensitive to interference/noise. I'd be very interested to know if you resolve the problem.
