Right. It happens with autoclose=0 too.
Any suggestions for the next step? Maybe add some instrumentation in the cdrom or ide-cd drivers?
I think I'll also go back to 2.6.26 for a while to see if I can reproduce it with that. I'm fairly sure it won't, but confirming that will be a good data point.
I don't see myself bisecting this as long as I don't have a reliable way to reproduce it.
BTW, I have considered a hardware problem like a short in the eject button, but I don't think that's it. The eject button "feels" good and I'd expect it to also spontaneously eject if that was the problem. It also does feel like there is a pattern to it, even if I cannot see yet what that pattern would be.
