I currently have a problem.
The problem is some mysterious sound like szzzz..... in very low tone and low volume.
However, it is noticeable and somewhat destructing.
I usually use 7.1-RELEASE, but as 8.0 being in BETA, I installed 8-BETA1 and BETA2.
Both of these versions has this noise.

The noise is very much like the same noise I experienced back in February.
At that time, you, Alexander, fixed the problem.
I had had used 8-CURRENT until end of April but I was away until this time.
Because the symptom was smiler, I decided to reply to the old e-mail chain.

Thanks,
Hiro
