I keep getting these errors every now and then, they seem to be linked to suspend/resume. The thing is, though, my system works fine with both Linux (Fedora 19 32-bit) and Windows 8 (64-bit), but processor context errors seem to always come with kernel panics and usually indicate faulty hardware according to the bit of googling I've done. This is on a brand now Lenovo B590 laptop... should I be worried? The prospect of having to send it back isn't terribly morale-boosting, especially given that I've already swapped the DVD drive for an extra hard disc. Some posts around the internet seem to indicate this is a bening bug caused by dodgy UEFI (and my kernel isn't tainted which I suppose is a good sign), but I still don't know what to make of it... anyone here experienced something like this?

I get them when my Phenom II is unlocked, been ignoring them for 4 years now and no problems. I asked all over, stability works fine in all test programs I could run. IBT, Prime, yadda yadda. So I decided to just get a new syslog system, syslog-ng, and it suppresses them for some reason. Which works for me, since I hate them popping up.

Mine was a cache error in the L2 cache? I dunno, swear that's what it was. All of them were corrected though, looks like yours is too? I dunno, if stability tests work fine and it doesn't corrupt something it might be fine. I know mine goes away when the cores are locked, so I'm sure something in one of my cores is broke but I'll run free cores till this chip dies. 4+ years now, I'll gamble. That and I've got an AM3+ board now, so if she dies I'll just get a cheap Vishera. haha

I dunno, if you think it's nothing install syslog-ng and it should suppress those.
