Bug Description
Hi,
I use an ACER TravelMate 8204 WLMi laptop. With feisty suspend did not work (but did power off the machine), and hibernate did work almost every time. Since I upgraded to gutsy, both suspend and hibernate show the following incorrect behavior:
- there is some disk activity (probably scripts from /etc/acpi/ executing)
- the screen changes to a text-mode virtual terminal
- then nothing: the screen remains on (black with a blinking cursor) and the fan is still spinning
Then the magic Sysreq key (Alt-Syst-b) does not work and the only way to turn the machine off is to press the power button for several seconds.
I am using the latest kernel version from gutsy:
$ uname -a
Linux vougeot 2.6.22-12-rt #1 SMP PREEMPT RT Sun Sep 23 20:27:57 GMT 2007 i686 GNU/Linux
$ cat /proc/version
Linux version 2.6.22-12-rt (buildd@vernadsky) (gcc version 4.1.3 20070831 (prerelease) (Ubuntu 4.1.2-16ubuntu1)) #1 SMP PREEMPT RT Sun Sep 23 20:27:57 GMT 2007
and the machine has an up to date BIOS from ACER. I will later attach information requested in
https:/
I tried again with kernel 2.6.22-13:
$ uname -a
Linux vougeot 2.6.22-13-generic #1 SMP Thu Oct 4 17:18:44 GMT 2007 i686 GNU/Linux
Results are slightly different but neither suspend nor hibernate does power off the laptop:
- suspend locks the screen and then nothing happens. Il can unlock the screen and continue to use the laptop.
- hibernate behavior is still the same as in kernel 2.6.22-12. I have attached a new kern.log with a hibernate attempt.
