Hi all.
I have got laptop Acer TravelMate 8004LMi (Intel Centrino, CPU Pentium M
Dothan 1.7 GHz, graphic card ATI Mobility Radeon 9700 - see more at
"http://www.laptopshop.co.uk/Acer-Travelmate_8004LMI-laptop-1-nd2.htm";)
and I have an ugly problem:
A few days ago I have upgraded to the Debian Etch and nowadays when I
switch from the X.org (7.0.0) to the text console (or into revers order),
a kernel sometimes totally freezes. It does absolutely randomly, sometimes
on 16th switch, sometimes on 158th switch... and only black screen I can
see. I have tried various kernel versions (2.6.10, 2.6.15, 2.6.16, 2.6.17,
even vanilla 2.6.16.28), some experiments with ACPI parameters (acpi=off
noapic nolapic), various X.org graphic drivers (fglrx, vesa) and text
console with framebuffer and without.
Previously I have used the Debian Sarge (kernel 2.6.10, XFree86 4.3.0).
The behaviour have been similar, but only picture have disappeared (and
have been black) and I have needed to do a next few switches (between
console and X server) and picture have revived. But now a kernel totally
freezes and reset is the only thing that I can do.
It is strange when I take old kernel 2.6.10 (that I have used in Sarge), a
kernel freezes even so. When I use vesa X.org driver, a kernel freezes
exactly after 7 switches to the X server and back to the text console.
With fglrx it freezes absolutely randomly.
I am very confused by this strange system behaviour and I have no more
ideas what to do to find a solution of this trouble.
Thanks a lot for any advice.
