Tagged Queuing Failure - Happy to provide further diagnostics on request

Software

RELENG_4 cvsup from morning of Sun Sep  8 2002

----------------------------------------------------------------------------

Hardware:

Intel D815EEA desktop motherboard.  Onboard ICH2 ata controller.
80 Conductor cable on both channels.  No failure from many months of uptime
before hw.ata.tags enabled.  PIII 800 / 256Mb PC133 SDRAM.

----------------------------------------------------------------------------

How to reproduce:

Occured twice.  I was using dump from ad0 -> a file on ad1.  At the same
time, I was browsing some large .jpg's on ad0 using xzgv.  On both occations
the dump had been running for several hours before the failure.  The
simultaneous xzgv appeared to be the trigger.
