Lion had its glitches but it was ok. Updated to 1.7.1 or 1.7.2 recently, whichever one is out right now, and since then have gotten 3 kernel panics. Two just random ones while doing light computing, the third during a bootup that failed. Also, while trying to get my small server software on it running, it started getting glitchy. So i attempted a restart; it turned off, bonged, and then stayed at a gray screen for 3 minuted before i turned it off. Turned it back on, everything was fine. Should i be worried or is this an issue with lion?
