This tells me that your RAM is generating correctable ECC errors. I.e., it
might be going bad.

You don't see them on Windoze because it probably doesn't report them there
- it doesn't mean that they don't happen. But I have no clue what Windood
  does.

You can check whether you have 

[    1.419829] RAS: Correctable Errors collector initialized.

in your dmesg - that thing collects ECCs and does not report them until they
become fatal. When they do, the machine will freeze and I don't think the OS
matters in this case.

You could send a full dmesg from the latest upstream kernel and I could take
a look but it needs to be the upstream kernel - for Fedora kernels you need to
go talk to them.

HTH.
