           Summary: Trying to restore saved vm.  Get xen_blk: request_irq
                    failed (err=-16)
           Product: Xen
           Version: unstable
          Platform: x86
        OS/Version: Linux-2.6
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Guest-OS
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: madams@xxxxxxxxxx


I use xm save command to generate vm dump.  I then use xm restore to restore the
vm to running state.  Vm is restored.  I run xm console  but I get the error
message that I listed in the summary of this report.  I then can not do anything
with the vm.  If I have logged into the vm before save, I can get back to the 
shell prompt, but if I try to issue commands, the console appears to hang.  It
seems to be getting the -16 error from the setup_irq function that is called
from request_irq.  Is there anything I can do to provide more information that
might be helpfull in diagnosing this?
