Well, interesting, but not the solution. I'm logged into Lightning, |
28 |
the AMD64 machine, remotely in two terminals. One terminal is running |
29 |
QJackCtl, a small X app that allows me to start and stop the Jack |
30 |
server, along with make connections, etc. |
31 |
|
32 |
In a second terminal I log in as root and start an emerge of a couple |
33 |
of things that don't get built - a new kernel tree and firefox-bin. I |
34 |
don't immediately get xruns, but when heavy disk operations start I |
35 |
do. Some of the xruns are over 100mS - absolutely huge when you're |
36 |
trying to run at 3mS! |
37 |
|
38 |
What's interesting to me is that I Can stream a movie from the EIDE |
39 |
DVD drive on this machine and never create an xrun, but as soon as I |
40 |
start using the SATA drive I do. That seems to be a pretty good clue I |
41 |
think. |
42 |
|
43 |
It's a good idea though. I'll keep looking into it. |
