[asterisk-users] dahdi_test drops after restarting Sangoma driver

[Andres]

Hi,

Does anybody have an idea as to why dahdi_test results drop to 
unacceptable levels after doing a wanrouter stop/start using a Sangoma 
card?  See below that it drops from 99.99% to 98.55%:

It has to do something with starting the driver from the command line.  
If I start from boot or via a cron job, the value goes up to 99.99%.  
I'm stumped.
