Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Two weeks ago, I installed Maverick on my former Win7 workstation and since then almost every session ends with a freeze and the REISUB trick.

I have taken the advice from previous questions of this type (RAM test, hard drive test), but none of them yielded anything.

However, when I use REISUB after a freeze, I sometimes see a lot of ext4 errors saying something about journaling having failed.

My hardware is fairly ordinary, I use a Huawei GPRS modem and a Nvidia video card.

I'll be forced to switch back to Windows (where everything worked flawlessly, which makes a hardware failure unlikely IMO) if this doesn't get resolved - something which I really would like to avoid. Any help is appreciated!

I have written down the errors I got last time the problem happened. They were of the form

[TIME] end_request: I/O error, dev sda, sector XXXXXX

I received several hundreds of them.

If it's possible to take a picture of the screen that would really help, someone with enough rep can inline it for you. –  Jorge Castro Oct 21 '10 at 18:59
    
Something of interest in /var/log/messages (you can use dmesg the output the contents of that log on the terminal)? –  Bobby Oct 21 '10 at 20:11

If your hard drive isn't dead by now (I too suspect it's a failing hard drive), then please install the package 'smartmontools' and run sudo smartctl -a /dev/sda from a gnome-terminal and post the output. –  htorque Nov 12 '10 at 5:05
    
This question should instead be filed as a bug report, thanks! Instructions here. –  Jorge Castro Feb 4 '12 at 20:05

Sounds like your hard disk is failing - that's what those error messages mean. Time to ensure that your backups are current and buy a replacement disk before it fails completely.
