Hello.

After having updated my OpenSuSE 13.2 system to

# uname -a Linux linux-8dae 3.16.7-21-desktop #1 SMP PREEMPT Tue Apr 14 07:11:37 UTC 2015 (93c1539) x86_64 x86_64 x86_64 GNU/Linux

I'm getting some new error messages

[ 4.530621] bbswitch: version 0.8 [ 4.530630] bbswitch: cannot find ACPI handle for VGA device 0000:01:00.0 [ 4.530633] bbswitch: No discrete VGA device found

PCI device 01:00.00 is a

01:00.0 VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1)

And also sometimes I get

[ 7740.061204] nouveau E[ DRM] GPU lockup - switching to software fbcon [ 7744.197641] nouveau E[ PFIFO][0000:01:00.0] SCHED_ERROR [ CTXSW_TIMEOUT ] [ 7744.198170] nouveau E[ PFIFO][0000:01:00.0] PGRAPH engine fault on channel 1, recovering...

I'm using nouveau as in the past I did have a lot of issues with the nvidia driver (i.e.with OpenGL). Sometimes the problem is really severe and the graphical system hangs (however remote logins (ssh etc) are still OK).

If previous kernel version works reliably and updated kernel version not you should open bug report about this issue. But we cannot exclude hardware issues as well.

By googling/searching I could not find any hint on how to solve the two issues on OpenSuSE 13.2.

Tnx in advance for your help.

Marco
