Do you see the spinning cogwheel on the console before you push the power button?


If so, there is an outstanding bug with file locks (IIRC) on OSX causing this problem at reboot time. We have it happen on our XServes fairly often.

P.S. Managed PDUs allow you to be lazier ;)


I've experienced this behavior as well as something much worse: kernel panics:
panic: vnode_put(...): iocount < 1



Are these being recorded in the /var/log/system.log file, because I am finding nothing useful there? If anything you would expect a crashdump.



The last system.log entry previous to the panic would be this:
Nov 8 03:14:57 sn-raid cp: error processing extended attributes: Operation not permitted


There was also talk of it on the Darwin-kernel list, as well as a patch to the xnu sources to correct the issue:
http://lists.apple.com/archives/Darwin-kernel/2005/Oct/msg00078.html


I was expirencing both reboot-freezing and panics... Although unsupported, I've since compiled a custom xnu kernel with the patch and the problems have went away.

I filed a bug report with Apple a month ago today (Nov. 8th). It's state is still open...
