My new Mac Pro 2008 is now doing the occasional reboot on wake from sleep.
Called Apple today. The nice lady said.
This is a known problem.
Engineering is working on it.
It is a software problem.
My name is now on a list to get an email as soon as a fix is available.
She did not recommend that I try to fix it myself in any way.
Sorry but please work around the issue for now.
OK, I can live with this minor issue for now.
Interesting. When I spoke to Apple I was quickly transferred
to level two. They also said it was a known problem and the
machine would have to be repaired. Naturally, I asked for a
replacement instead. I'd be pretty annoyed if it turned out to
be a software problem because the replacement I have now
seems to be faulty.
