My problem is on i386 version of 7.2-RELEASE-p2 on Intel Atom 330 CPU. And my system just panic randomly with "spin lock held too long". It didn't panic at reboot or shutdown so I think it the problem is somewhat different from that mentioned by Barbara's PR? Anyway I disabled powerd and it seems become stable now. And I am sorry that my system has been put into service so it would be hard for me to switch to -CURRENT... :( Regards, C.C.
