Still facing the issue with kernel 4.2.0-23-generic, gcc version 5.2.1 20151010
(Ubuntu 5.2.1-22ubuntu2), bbswitch-dkms 0.7-2ubuntu1, no bumblebee package
installed. I attach a full dmesg (from kern.log) from the boot to the freeze.
After booting, I logged into tty1 and entered the following
Do you have a full dmesg since the first boot? I have seen machines
having issues due to hotplugging where the device is gone during
suspend.

For me on my UL30VT with ubuntu 15.04 it was:
gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13)
And cat /proc/version
Linux version 3.19.0-15-generic (buildd@komainu) (gcc version 4.9.2 (Ubuntu

This problem may occur when your compiler (gcc) is different than the
one used to compile the kernel. Have you installed an older gcc version
(maybe via CUDA?). What does `gcc -v` show?

bbswitch prevents suspend and taints kernel

What else information is needed?
I have tried with the daily kernel 3.17.0-999.201409272205 and the tainting
still occurs. The syslog trace related to suspending event is slightly
different (dis_dev_get+0x15/0x40 [bbswitch] instead of
pci_bus_read_config_dword+0x64/0x90 in the initial report
$ sudo modprobe bbswitch load_state=-1
dmesg log:
[ 2780.584599] bbswitch: module verification failed: signature and/or required
key missing - tainting kernel
[ 2780.584809] bbswitch: version 0.7
[ 2780.584818] bbswitch: Found integrated VGA device :00:02.0:
\_SB_.PCI0.VGA_
[ 2780.584830]
Disabling the graphics card seems to trigger an ACPI hotplug event which
seems to remove the device from the system.
Could you prevent bbswitch from loading at boot (nvidia/nouveau should
not load either), then report the output of the following steps
including a dmesg log:
sudo modprobe
Still apears with linux-image-3.15.0-031500rc5-generic.
For now, I stay with 3.11 kernel from kubuntu 13.10.
