[Pkg-virtualbox-devel] Bug#578863: virtualbox-ose: Very low performance. "echo 2 > /proc/..." does NOT fix the problem

[W.GV]

Package: virtualbox-ose
Version: 3.1.6-dfsg-2
Severity: important

During booting there appear this message that could be related to the very very
low performance of the system (so slow that it is impossible to work with it):
[   24.718446] vboxdrv: Trying to deactivate the NMI watchdog permanently... [
24.718452] vboxdrv: Warning: 2.6.31+ kernel detected. Most likely the hardware
performance [   24.718454] vboxdrv: counter framework which can generate NMIs
is active. You have to prevent [   24.718456] vboxdrv: the usage of hardware
performance counters by [   24.718458] vboxdrv:   echo 2 >

timer mode is 'normal'. [   24.727191] vboxdrv: Successfully loaded version
3.1.6_OSE (interface 0x00100001).   Nevertheless I cannot do "echo 2 >
/proc/sys/kernel/perf_counter_paranoid" because this file does not exist in my
computer. There is another one, though, "/proc/sys/kernel/perf_event/paranoid"
.. If I change this last one, I cannot notice any better performance.  Thank you
very much !
