Sorry, I didn't receive the last 2 msgs in my mailbox, (especifically the
questions Ingo asks me). Here the answers:
a) Yes, I am using iceweasel.
b) my phisical RAM is 8 GB
The related kernel info is below, first kernel 3.5 related and then
standard wheezy 3.2 kernel related. Note that with kernel 3.5 I don't
have the "MTRR allocation failed" error.
My integrated graphics BIOS configuration:
Virtu Technology [Disabled]
Integrated Graphics Share Memory [64MB]
DVMT Memory [256MB]
IGD Multimonitor [Disabled]
