Just wondering if anyone else has come across an issue where files cached in memory appear to become 'corrupted' - for example, on one workstation, I've just had the issue:
There is a kernel bug for this kind of problem but it is for AMD x86_64 only: http://bugzilla.kernel.org/show_bug.cgi?id=7768 . Since you are reporting this for i686 as well, I'm not sure it's the same thing. The symptom is that an entire 4k cached file block is trashed. This was fixed upstream for 5.x: https://bugzilla.redhat.com/show_bug.cgi?id=238709. I cannot tell if a similar patch has gone into a 4.x kernel: the appropriate RedHat bug (https://bugzilla.redhat.com/show_bug.cgi?id=223238) is unfortunately private. Someone could look at the latest kernel sources and see.
