Severity: important
This is really an upgrade report. I am upgrading from Squeeze to
Wheezy.
I am trying to support a site running Debian with many systems with an
ASUS F1A75-M LE motherboard. This hardware runs the Squeeze Linux
2.6.32-5-amd64 kernel without problem.
http://www.asus.com/Motherboards/AMD_Socket_FM1/F1A75M_LE/
Unfortunately upgrading to Wheezy or later is a complete fail. The
kernel is generally usable and installs and boots okay. But part way
through the boot process with text characters being displayed but then
the display switches into a ~60% snow ~40% white and becomes unusable.
To be clear this is the vt console. This is not the X Window System
display. The Linux vt console is unusable.
On Squeeze's 2.6.32-5-amd64 kernel all works (mostly) well. When
attached to 4:3 aspect ration monitors up through 1600x1200 all works
fine all around and no problems were ever logged. It turns out it is
using the vesa driver for this function. It worked well. (However
changing the monitor to a 16:10 widescreen monitor causes the vesa
driver to fail and fallback to the fbdev driver. The fbdev driver
tries to drive the 1440x900 monitor in 1280x1024 mode and looks
terrible. Therefore I attempted to upgrade to the Wheezy and ran into
this problem. This is parenthetical background information only.)
Since the vt console works on Squeeze but fails hugely on Wheezy I am
calling this a regression. It isn't possible to use Wheezy on a
system that used to run Squeeze. Since this is the Linux vt console,
not X, there isn't even the proprietary driver to try.
I will happily provide additional information. At the moment I don't
know what I would add. Any hints?
