Last night, for the second or third time since I upgraded from C6 to c7 this summer, I did something on firefox - I think it was reload a page, and my system rebooted. Yes, I have a ton of tabs open. I see nothing suspicious in /var/log/messages, or in /var/log/dmesg.old. I saw a mention of boltd? I think, but nothing more. Has anyone else had this problem? mark
