I've had an acer aspire laptop for a little over a year now. For the most part it works great, however once every couple of weeks or so it starts acting up and I need to do a hard re-boot.
It's running Ubuntu 11.10 amd64, but the same situation occurred prior to the update when I was running Ubuntu 10.01 x86.
I'll be running multiple apps for work, web browser, thunderbird, sql monitor, terminal, etc. And a program will crash, basically just stop running and disappear. Then when I try to interact with any other programs they are unresponsive or they also crash.
When I try to logout or restart from the unity panel it does nothing. When I go into a virtual console to attempt a reboot as the root user I get a laundry list of errors stating 'bad sector' information. And the prompt to login is presented again.
This ultimately leads to me power cycling the box.
I'm wondering if anyone has had this happen to them? I've reviewed the hard disk thinking that had something to do with it and the smart tools monitoring doesn't indicate that's the issue. Then I started thinking maybe my ram is bad. Is there any method of testing the machines RAM to verify it isn't corrupt.
