Red Hat Bugzilla – Bug 802193
Linux kernel does not boot properly on new Samsung laptop series 7 model 700Z4AH
Last modified: 2012-11-02 09:14:15 EDT
Description of problem:
I just bought a brand new Samsung laptop. I have installed Fedora
Linux boot has error message
Then it seems to work fine when I am using a mouse, but the touchpad does not
work. Sometimes not well, sometimes not at all...
As soon as I use a USB mouse, the mouse works.
>> uname -a
>> Linux qingwei 3.2.9-1.fc16.x86_64 #1 SMP Thu Mar 1 01:41:10 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Version-Release number of selected component (if applicable):
Fedora 16 with Linux kernel 3.2.9
Steps to Reproduce:
1. Install Fedora 16 on a new Samsung laptop series 7, model 700 Z4 AH
2. there is an error on boot message
3. the touchpad does not work well
no error message at boot time
touchpad should work
I forgot to mention the linux boot error message is the following
pnp 00:0b can't evaluate _CRS 12311
Can you attach full dmesg output please?
There are only 3 lines
First I get
Loading Fedora 3.2.9-2_fc16.x86_64
Second line is
Loading initial ramdisk...
and then the third line
[0.484696] pnp 00:0b: can't evaluate _CRS: 12311
The time at the beginning changes each time I boot...
After that the kernel boots however normally, I can login but I have
bad touchpad (press and drag to move windows does not work)
and as soon as I go in system settings to change anything in
the touchpad, then it freezes and I cannot move the cursor anymore,
no click either, it is completely frozen...
I can only logout using the keyboard
When I use an external USB mouse, apparently no problem.
The battery goes out quickly however.
I can work 6 hours with Windows 7 but only 2 hours with Fedora
If you send me a debug kernel I can send more info...
can you please attach the output of the dmesg command once logged in?

I have the same problem. My notebook is a Samsung RC420 and when my fedora starts this error 'can't evaluate _CRS' appears. Everything work fine except the touchpad.

Linux localhost.localdomain 3.3.0-4.fc16.x86_64 #1 SMP Tue Mar 20 18:05:40 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
I upgraded like bruno and same result
Linux qingwei 3.3.0-4.fc16.x86_64 #1 SMP Tue Mar 20 18:05:40 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
and same problem with _CRS and touchpad does not work.
To be more precise, I can move the mouse cursor with the touchpad,
I can have a menu with <left button click>
but cannot drag. When I press left button the mouse cursor freezes
I have attached the new result of command 'dmesg' with kernel 3.3.0

I have upgraded to 3.4.7-1.fc16.x86_64
Same problem, same symptoms
error message at boot time: can't evaluate _CRS: 12311
and touchpad does not work
There are a few changes to the elantech driver in the 3.5 kernel that might help the issue. Have you tried Fedora 17 on this machine at all?
