Hey,

I have a question about hardware errors. I have 3 BIF running under ubuntu / bfg 3.9 with 15 BEEs...
The hardware issues are droping the performance, here is an extract after running for 22 hours. Any ideas whats up? Couldn't be temperature and it is plugged into a 10 port USB 3.0 hub with 7 BEEs... Had the same data when they were in the same hub with 3 BEEs.

3.9 % is okay IMO, but 11% and 15% are too high? Using default settings (no changes to the Oscillator bits).

Thanks

How are you sure it isn't temperature? Mine is running >10º C less than that. Do you have any fans on the assembly? Before I put one on mine I had failures all the time.
