I think I'm suffering from the same issue. I was archiving my home in 1 tar file from 1 disk to another (all EXT4) and then it got stuck. I had to restart the computer and eventually it proceeded, but I have to say, after I copy large files, the chances I can't read/open other large files are high.
Basically as long as I don't copy/manipulate large files I don't have particular issues; as soon as I try to do such operations I have to restart my pc. I'm using: 2.6.38-11-generic #50-Ubuntu SMP Mon Sep 12 21:17:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux I have to say I have a pretty vanilla Ubuntu, no customization. I'm thinking about Ext4 issue because 6 months ago all my disks were Ext2 and never had an issue, but now looks like an issue after another. Did a memcheck and it seems definitely ok. Unfortunately it's very hard to reproduce systematically.
