Over the last couple of months there has been multiple postings relative
to changing the pci latency associated with the disk and pstn interfaces.
General comments tend to suggest the disk can consum hugh amounts of
time, impacting ethernet and/or pstn interfaces (and thus audio).

I've not played a lot with the latency settings, but understand its a
balancing act between specific devices on _your_ system (not necessarily
anyone elses). If you execute a "lspci -v" (as an example), you'll see
the current pci latency settings.

Google should find several references.
