hmm. I don't know if I'm in the same experience or not. I'm running fedora 21 and upgraded to kernel 4.0.8 from 4.0.7 on 7/19. I didn't have any issues until about the 26th. But then my system started to lock up. It wasn't just GNOME but direct access was locked -- ie no response via keyboard, no signal to monitor. The system responded to ping and allowed nfs shares that were in place but was not accepting ssh connect. So I powered down and selected kernel 4.0.6 on the reboot on 7/29. I haven't had any issues since. However, I am not seeing any kernel bug events logged in the journal. I suspected the seagate USB drive or driver for a minute but before I dropped the kernel back I unplugged the external drive. Still locked up. I am seeing some references to nVidia in the logs.
regards,
Joe Verreau Durand, MI

This is happening every few minutes since I updated today:

Going to try booting the previous kernel.
This is likely a bug. Please file on BZ so that developers may know about it.
It's wierd. I rebooted with 4.0.8 (which had previously been working with no issues) and got a different bug:
Jul 30 18:54:49 Bree kernel: kernel BUG at mm/slub.c:3413! Jul 30 18:54:50 Bree kernel: invalid opcode: 0000 [#1] SMP
I rebooted again with 4.0.6 and so far it seems to be working (several hours without crashing).
I'll try updating again tomorrow before I report anything.
