It was, what fs are you using for /tmp?
Another thing that may help is tuinng the disk elevator with elvtune(8),
the latencies are set pretty high by default, especially for scsi disks
that have thier own block grouping code.
Reducing it will reduce throughput, but may help things get written out
the disk earlier and reduce burstyness.

Steve,
I hesitate to take this thread in a different direction, so let me just
ask if this problem is possibly card dependent, or something that has really
been caused by recent changes to Jack?
I have not been able to run Jack now for months, but 3 months ago, when
I was running Jack daily, I had my system on an ext3 drive and audio going
to a reiserfs drive, and with my HDSP 9652 I never once saw an xrun at any
latency setting of 256 or above. I might periodically get one at 128 and
would get a few more at 64. All of that under KDE using RH 8.
Actually, I have run Jack over this period, but only using the on-board
sound chip, so that's pretty useless to me for anything other than looking
at GUI interfaces, but with that driver (snd-via82xx) I did see xruns.
Why did I not see xruns with the HDSP 9652?
