I can reliably reproduce the error by mounting the filesystem with CIFS fscache enabled, then doing a cp on a file, and then hitting 'ctrl-c' to cancel the copy. This is on a separate VM with RHEL6.4 using the 373 kernel. If I let the copy finish on its own, no error is generated; if I cancel the copy, it dumps 'bad page status' in dmesg. Maybe aria2c generates these errors because torrents work in file chunks, so it opens, seeks, reads a chunk, and then closes. The kernel code may not handle partial reads properly, I speculate. The crashes that happen after a while could be a separate problem.
