Bug#683807: R: Bug#683807: R: Bug#683807: R: Re: Segfault while using mv/"fusermount -u" with sshfs share
Hi,
This morning when you sent your message i disabled bumblebee and nvidia, i
rebooted and then i verified kernel.tainted.
The value was 0. (ok)
But today,
I suspended-to-ram the notebook and i resumed after 2 minutes. Now , almost 30
minutes later, iceweasel crashed 3 times,
each time it crashes just a few seconds after the launch.
I noticed this in the syslog: (time is italian time) :

and kernel was tainted:
kernel.tainted = 4097
so i opted for a complete uninstallation of bumblebee
apt-get remove bumblebee bumblebee-nvidia
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer
required:
bbswitch-dkms libglu1-mesa virtualgl virtualgl-libs virtualgl-libs-ia32
Use 'apt-get autoremove' to remove them.
The following packages will be REMOVED:
bumblebee bumblebee-nvidia
0 upgraded, 0 newly installed, 2 to remove and 0 not upgraded.
After this operation, 222 kB disk space will be freed.

and then apt-get autoremove
now the "No NVIDIA graphics adapter found!" messages have stopped appearing.
could the bbswitch module itself be the cause of those segfaults?
note: i was connected via wireless when the problem appeared. browser is
iceweasel 10.0.6 connected via Tor and using torbutton
I had very similar segfaults recently (~ 1 or 2 weeks ago) with transmission-
gtk. Also in that case it was a simple segfault (with "Segmentation Fault" in
the xfce4-terminal) without any traces about that in the syslog.
i've just rebooted now, uptime was 11 hours.
After the reboot i tried to suspend-to-ram and there're no 'No NVIDIA'
messages in the syslog this time.
Asdrubale.
