I have installed Fedora 20 on a new Dell OptiPlex 9020 workstation. I use about the same software set that I used on an older Dell and with Fedora 19 that was very stable. With Fedora 20 I have had several kernel crashes. I only have pictures from the console after the crashes. The crashes are not similar. Dell's own diagnostics and Memtest86+ 4.20 did not found any issues from the memory.

Kernel versions that have crashed: 3.11.10-301.fc20.x86_64 (crash1 & crash2) 3.12.5-302.fc20.x86_64 (crash3)

I'm using bcache (naturally did not use bcache in Fedora19) and VirtualBox (Fedora as host).

Dmesg after boot can be found here.

If this is graphics related, then here's the relevant part from lspci:

Though I'm mainly using the system remotely (ssh + vncserver), so local display is just showing login screen.

Noticed also some new messages from dmesg, no kernel crash yet...

With later kernel (3.12.7-300.fc20.x86_64) the system has been stable for at least five days.

iommu=memmaper iommu=soft vga=normal vesa=0 in /etc/grub Try these if you having problems. one should work! I have new AMD 64bit system and found that linux has trouble with nvidia and dma setting caused by iommu settings in bios, so set in grub fixed for me. Just read this ftp://download.nvidia.com/XFree86/Linux-x86/270.29/README/dma_issues.html (paste to browser)

Had a similar issue as the OP posted crop up last month after an update on my AMD APU based system and adding these options seemed to have solved the problem. I'd upvote but do not have the rep to do so as I just signed up on this site
