I am running 2.6.32 and am faced by exactly this problem on
a machine I cannot just reboot:

  % ps aux | egrep -c '\<D\>.+vgdisplay'
  37821

lsof or strace on existing processes don't show anything, but strace
on a new vgdisplay process shows that it blocks on opening
/dev/cdrom, which seems to be defective.
