I updated my Raspberry-Fedora after a long time, before upgrading operations were very slow, after a long battle to uprade, now it works fine.
I have never experienced a full block of my system but I have never run my Raspberry for more that five hours. Tonight I noticed that after login and after a while HDMI was shut downd and my tv-set became blank, I had to rechoose on my TV-set. Not clear about this issue, and I think not connected to updated kernel


The HDMI sleep issue isn't connected to the kernel update. It existed prior. However, if all is working right tapping the keyboard will start up the display again. I don't know if the symptoms changed much. Mine goes idle after like 5 minutes and then the TV automatically shuts off a few minutes later. 

I haven't idled with the new kernel enough to know whether the original issue has been fixed yet. But it hasn't occurred.
