Hm. There were bugfixes that went into the kernel for Logitech Unifying Receiver issues. I can't recall if they introduced more problems or not.
Kernel 3.11.7-300 problem not fixed

Actually, my best bet would be to test commit ce7373685ec33b94c293d9cfdb46daecb22db261, which is in v3.12. The patch is here: https://patchwork.kernel.org/patch/2836578/ I'm not sure if we already have some 3.12 kernels in Fedora, but it worth the try.
When kernel 3.12 landed into Fedora 20 repository?
You could try this and report back: http://koji.fedoraproject.org/koji/buildinfo?buildID=477387
Fedora 20 will get 3.12 around the 3.12.1 release. We're maintaining the 3.12 kernel in the rawhide nodebug repo, so you can use that if you'd like as well. The link Michele provided should be fine though.
Good news: problem with Logitech Unifying Receiver is gone with kernel 3.12. Bad news: problem "Poison overwritten" still here. https://bugzilla.redhat.com/show_bug.cgi?id=1033948
Thanks Mikhail. Josh I guess we can put this one in MODIFIED until 3.12.x hits Fedora then.
