I have been noticing frequent system hang for more than a month on my Laptop(G580). However the frequency increased to every 30-45 min recently.
I can't generate a crash after the hang as nothing works, I have to do a hard reboot.
I tried to generating a crash using Ctrl’+'Alt’+'SysRq’+1 followed by Ctrl’+'Alt’+'SysRq’+t, but no use. Finally I had to do a hard reboot.

Please help me fix this issue; Do let me know if you need any help from me.

The following are the system and package information of my laptop

I have just updated my Ubuntu 12.04, and I'm experiencing freezes too. Total system lockup. The only way out is to hard shutdown my laptop. I'm using a sysmonitor program and it's on the taskbar, and it's showing high usage, CPU > 85%, whenever this happens.

Thanks!

As I mentioned in my previous update, i could not restart the machine with magic keys even after configuring kernel crash-dump and SYSRQ parameters. The only way out is hard reboot using the power button. Due to this I am not able to find the package specifics.

Hi Fabio: Is it OK if I provide you the requested log files after hard reboot.

Additional observations
I have noticed the freeze mostly when working with any browser(firefox, chromium), skype, printing and eclipse.

However I can continue my work with a windows virtual machine running on KVM.

Thanks for your time.

[Fabio Marconi (fabiomarconi)]

Yes, attach the files after the reboot

I am having same laptop -> G580 with 4GB ram and core i5. I am seeing the same issue. System abruptly freezes at random intervals, even on light/medium activity. The only way out is hard reboot using the power switch.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Janak Porwal (jp19online)]

I had to do 2 system reinstalls because of this (and another bug that renders my data card useless if system is rebooted without disconnecting data card). In first attempt, problem seem to vanish after removing unity3d and preserving with 2d. But in latest install, I am facing this even when running unity 2d. Read somewhere that someone with another Lenovo model managed to fix the problem after 1 months of experimentation, by turning off BIOS CPU power management. However, in my laptop (g580), I don't see any option in BIOS regarding CPU POWER Management.

There has been no activity here or mention of similar issues in years and it's likely resolved, closing but feel free to open a new report if you still have problems in newer versions
