We're seeing a reproducable kernel oops on a particular system when 
accessing a set of files. We're using ext3 file systems. Has anyone seen 
this on SL4, kernel-2.6.9-11.EL, i386?

We've run memtest86 for ages on the system, and haven't found anything 
wrong.

Any idea whether this can be filed on redhat bugzilla as RHEL4?

Thanks

Jeremy
