attempt to access beyond end of device

[David Titzer]

Seeing the following paired kernel error messages:

"attempt to access beyond end of device"
"dm-1: rw=0, want=26553873480, limit=3786932224"

The server is a PE2950 running RHEL ES 4.4. The system has one filesystem under LVM, physically living on an AoE storage server. AoE drivers are up-to-date. Server exports the root of that logical filesystem to other servers. The server's kernel is 2.6.9-42-ELsmp.

We are seeing odd small-file corruption. Sometimes, this corruption occurs to static data files after being accessed for read. 

I've not seen info related to this problem on recent Red Hat releases, or recent kernels for that matter. 

I could use a good starting point for troubleshooting this! This isn't the only AoE installation I'm working with, but it is the only one using PE2950s, and the only one with such errors. Thanks.
