BOTH 7606 Power Modules being disabled - But still running!

Anyone ever see this before? We've been having alarms for the last week or so complaining that one of the power supplies has had a failure. Shipped a new PS, and was going to have it put in, when we noticed the other PS started alarming as well. And both are alarming at the same time. 0 watts available. But... it's online! Weird. 7606, running an (admittedly old) IOS 12.2(33)SRB3 and year and a half uptime. We're afraid of rebooting the thing, and obviously don't think swapping out power supplies will help. Backplane issue? IOS bug? Or is this stuff controlled on the supervisors and replacement/switch will fix? A brief Googling, bug search, and looking through these forums hasn't brought up much. Any help is appreciated!

Your IOS is within the ones affected, not sure if this is the problem but would be nice to try to upgrade it.
