Just wondering if anyone else has come across an issue where files

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.
Thanks for the info - the machine I recently noticed this 'yum' issue is
a Supermicro X5DA8 with 2 x 3Ghz (32 bit) Xeons - so not a AMD x86_64
issue - as that kernel bugzilla issue seems to be about ...
Anyway, I'll keep poking about ...
Thanks
