Untraceable stability problem of 3.6.8 kernel on ASUS P53E

http://unix.stackexchange.com – Randomly, but not later than after 10 hours of work, the laptop freezes. Just freezes. Knowing that not all hardware errors are reported back to the user I tried the netconsole. Unfortunately the netconsole also didn't output anything at the time of freeze. The only correlation I've found is that usually, on next powering up (after forced powering off) the laptop consumes 10W more power. But I suspect it might by a concidence; this behaviour is not limited to the times, when system was powered on after the freeze. After 1.5 (on average) times rebooting, the power consumption is back to norma (HowTos)

Hello all.

I have a big trouble with Ubuntu 12.04.2 and 12.10. After boot all works fine. But an uncertain time, my computer freezes. Only hard power off work. I tried different kernels - have the same problem. Memtest86+ says: no errors on RAM.

Maybe you, guys, have some idea how to fix it or why this happens? Maybe someone have same laptop.

My Thinkpad T510 will freeze after anything from a few seconds to a few minutes after boot. I cannot do anything except hard power off the laptop. Sometimes it freezes at the login screen, sometimes at the desktop. So far it hasn't frozen on boot. I'm using Gnome 3 and GDM. Laptop-mode which is enabled on battery and AC power.

I have a Inspirion 15r laptop, with intel integrated graphics card.It works fine, but, sometimes, generally when I plug/unplug laptop from power, than, the powerdevil change brightness...

Hi all!

I have a problem with my computer (Ubuntu 11.04, x86_64, Kernel 2.6.38-11-generic). In random intervals it freezes completely. Sometimes about once a week, sometimes several times a day. Only a hard reset will bring it back to live then (tried to ping/ssh it from another machine, didn't work).

that doesn't explain why it freezes. in case of power supply laptop should be dead or reboot itself, not freeze

Fedora 10 freezing my laptop 3 years 32 weeks ago

hey all, i loaded Fedora 10 onto my Lenovo T60 last week. everyday i boot it up and it works fine for a few minutes, then freezes. to the point of powering off. my mouse still works but nothing else. i power back up and it generally stays up after that.

Random system freezes 2 years 4 weeks ago

So, the freezes are still there. I also tried the open source ATI driver. My laptop will still freeze randomly. The highest freeze rate was during operations with pacman/clyde. I think this might point to either WLAN or HDD. I placed a desklet clock on my desktop and I could finally see the exact time when my laptop froze!

I have this remote Ubuntu 12.04 minimal headless server which I access and manage over reverse-SSH-tunnel (because it's behind a NAT firewall).

However, the issue I'm facing is, that randomly it cannot be accessed, whether remotely or over the LAN. When I say random,at times it can go for days and at times it doesn't go for more than 24hrs.

At first I thought it was maybe a power-saving thing or

I installed netconsole using the instrunctions given here:

https://wiki.ubuntu.com/Kernel/Netconsole

dmesg | grep netconsole says everything is OK, but I won't believe it so easily:)

How can I make Ubuntu generate some kernel message in order to see if netconsole really works and sends everything to the other computer? I tried:

logger -p kern.alert "test message" # this apparently talks to s
