Description Hetz Ben Hamo 2016-01-14 14:07:35 UTC

I'm using Fedora 23 (KDE Spin) on a Lenovo Ideapad S510P. This machine has both the intel graphics and nVidia 820M chip although I don't use the nVidia chip nor did I install anything to enable it (Bumblebee etc..)

With kernel 4.2.3-300 (the one that is shipped with F23) everything works fine. However, after doing an update, the kernel that is being additionally installed (4.3.3-300) - my machine boots, shows the Fedora logo being "filled" and then the machine is crashing, showing something which is related to nvkm.

I tried blacklisting the nouveau but it doesn't affect anything.

The only thing that I see on /var/log/messages related to this issue is:

Jan 14 14:39:28 localhost kernel: BUG: unable to handle kernel NULL pointer dereference at           (null)
Jan 14 14:39:28 localhost kernel: IP: [<ffffffffa02ca3e5>] nvkm_pmu_pgob+0x5/0x20 [nouveau]
Jan 14 14:39:28 localhost kernel: PGD 41a768067 PUD 4129fc067 PMD 0
Jan 14 14:39:28 localhost kernel: Oops: 0000 [#1] SMP

If there's any additional info needed, I'll be happy to provide it (/var/log/messages doesn't have the full panic so at best I can take a snapshot with my smartphone).

Thanks
