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.
