Subject: ALSA errors when renicing unrelated process
Date: Tue, 13 Jul 2004 21:08:42 -0400 [thread overview]
Message-ID: <1089767321.2729.4.camel@mindpipe> (raw)
I have found that I can reliably produce the following errors by
renicing the X server from -10 (the default on Debian) to 0 and back. I
get the same error going from 0 to -10 as -10 back to 0, as if renicing
the process causes some kind of hiccup in the scheduler. I do not seem
to get XRUNs when this happens.
