[Debian-eeepc-devel] Bug#778867: eeepc-acpi-scripts: Causes video corruption and freezes system when eeepc-acpi-scripts executes

[John C. Peterson]

Package: eeepc-acpi-scripts
Version: 1.1.12
Severity: important

Dear Maintainer,

I performed an upgrade of my Asus EeePC 1000 from Squeeze to Wheezy back
in November without any particular problems. The upgrade did NOT install
the eeepc-acpi-scripts package, but it seemed like an appropiate package
to have installed, so I later installed it manually.

I later began to experience a problem with video corruption (that I
had never experienced before) when the system was booting. It was not
reproducible, occurring perhaps 25% of the time. As the problem was
random in nature, I did not initially suspect the eeepc-acpi-scripts
package was related to the problem.

The corruption is best described as colored "snow" with *nothing*
intelligible on the screen.  None of the Alt-Fn keys would bring up
another VT, I could not login remotely using ssh. I could not coax
the system to perform a clean shutdown either, pressing the power
button, or hitting ctrl-alt-del did nothing. All I could do was
power down and reboot. The freezes were nasty enough that my /var/log
directory got thoroughly trashed on one occassion, with about 20 log
files ending up in /lost+found as a result of problems found by fsck on
the reboot.

It's worth noting that this video corruption also happened (just once)
during a system *shutdown* after the X11 server exited.

The messages at boot fly by so fast, so I installed bootlogd to better
understand the normal boot sequence. At that point, it became obvious
that when this problem happened it was when the eeepc-acpi-scripts in
/etc/init was executed. After purging eeepc-acpi-scripts from my system,
I have *not* seen the problem after well more than 20 boots.

Sorry I can't provide more helpful information, but /var/log/messages
and so forth contained nothing useful.

My system has slightly modified hardware:

ASUS EeePC 1000 (straight 1000, no letter suffix)
Intel Ultimate N WiFi Link 5300 (replaced the factory wifi card)
Upgraded to 2GB of RAM
