mmm...

If I ENABLE my discrete video card, as follows:

# echo ON > /sys/kernel/debug/vgaswitcheroo/switch 

And check the result, as follows:

# cat /sys/kernel/debug/vgaswitcheroo/switch 
0: :Pwr:0000:01:00.0
1:+:Pwr:0000:00:02.0

then wireshark starts correctly and works fine.

If I however DISABLE my discrete video card (using OFF),  an attempt to start 
wireshark results in a gut wrenching, really hard, hard crash, completely 
locking up my system, even beyond the Alt-SysRq-B reboot (which normally works 
as a last resort). Tried it several times to verify.

Have attached the relevant part from my syslog to this e-mail.
