 |
|
Hi,
I have a weired problem with my laptop that seems to freeze randomly with blinking capslock led. I can't do anything then except power of f with keeping the power button pressed...
So far, I didn't realize any specifc pattern when it happens nor does it seem to be related to any specific application.
Does anybody know what causes this problem and how to fix it? I googled a bit and realized that people running ubuntu reported similar problems but I couldn't find a satisfactory solutions.
And: I am not sure but I believe that the problem may be related to some updates during the last weeks since I can't remember having this problem right from the beginning... |

| That sounds like a kernel panic. What is the output of uname -a ; emerge --info ; lsmod ; cat /proc/sys/kernel/tainted? |

| Try to reproduce the problem with an untainted kernel or report the issue as-is to ATI. Since you have a proprietary kernel module loaded, it is unlikely that the upstream kernel maintainers will take much interest in the problem report if the problem only occurs when using the ATI proprietary driver. |

| Sorry, but I am not sure what you are talking about. What is an untainted kernel? |

A kernel that has a commercial module loaded is tainted. That's how I understand it from a few years back, someone correct me if I am wrong.
I think the thing that taints the kernel may be your fglrx module. |

| The module does not need to be commercial, but yes, in this case the proprietary module is the reason for the taint. Kernels can become tainted for other reasons. See kernel/panic.c around the function print_tainted for details. |

I did a little more research to clarify my knowledge of a tainted kernel for any passers by.
Novell had a good description:
| Quote: |
P: A module with a Proprietary license has been loaded, i.e. a module that is not licensed under the GNU General Public License (GPL) or a compatible license. This may indicate that source code for this module is not available to the Linux kernel developers or to Novell's developers.
G: The opposite of 'P': the kernel has been tainted (for a reason indicated by a different flag), but all modules loaded into it were licensed under the GPL or a license compatible with the GPL.
F: A module was loaded using the Force option "-f" of insmod or modprobe, which caused a sanity check of the versioning information from the module (if present) to be skipped.
R: A module which was in use or was not designed to be removed has been forcefully Removed from the running kernelusing the force option "-f" of rmmod.
S: The Linux kernel is running with Symmetric MultiProcessor support (SMP), but the CPUs in the system are not designed or certified for SMP use.
M: A Machine Check Exception (MCE) has been raised while the kernel was running. MCEs are triggered by the hardware to indicate a hardware related problem, for example the CPU's temperature exceeding a treshold or a memory bank signaling an uncorrectable error.
B: A process has been found in a Bad page state, indicating a corruption of the virtual memory subsystem, possibly caused by malfunctioning RAM or cache memory. |

| In order to come back to my problem I wonder if I my problem would be solved if I unlod this module (fglrx)? Since I am actually using another graphics device the module is not used... |

Probably. Or you could take fglrx out of Xorg.conf (unless hal is handling X's config for you).
How did fglrx get loaded? Is there an ATI card there but not being used or do you have something manually loading it?
I'm only asking because you said that you have another graphics device. |

In my xorg.conf I have the following lines. The fglrx is loaded but never used because so far it never really worked...

If you look at /var/log/Xorg.0.log it should tell you what's going on when it freezes.
Sometimes while it's frozen you can ssh into the machine to look at the log. If that's not possible, after reboot there is usually a backup log called Xorg.1.log or something like that which should have the info from the last use. |

| If the system is hanging due to a kernel panic, it is unlikely that meaningful logs will be written. You may be able to extract information via a serial console or netconsole, if you can get the kernel to print to them during the panic. Given that information, we might be able to identify what caused the panic. |
