Thanks for the info.
Yes sleep/wake I see a lot, so that might explain why, so this is down not
following the spec's.
Can you explain on why you cannot get to work, is that because cannot get
access to their technical data ?
Also I did see once a problem with G5 or Dual processor, was that an Apple
issue, which the vendors worked around in driver.
Thanks for this information as this now behind to clear my understanding of
this issue.
