           Summary: dom0 ACPI causes device freezing
           Product: Xen
           Version: unstable
          Platform: Other
        OS/Version: Linux-2.6
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Guest-OS
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: aliguori@xxxxxxxxxx
                CC: hohnbaum@xxxxxxxxxx


Symptoms

Since the introduction of dom0 ACPI support, xmms (an audio player) would
randomly stop playing (although remained responsive).  Even after restarting the
application, it would no longer be able to play audio.

Within the past two weeks, the problem has become more common and now when audio
stops working, the network interfaces also stop working.  The problem usually
occurs after playing sound for a few hours.

Platform

Xen-unstable from 20050613 back to Arun's initial patches.  The test machine is
a IBM Thinkpad T41p and the ibm-acpi module is loaded in dom0.  I'll also attach
the kernel config.

Advice on how to track this problem down would be appreciated.
