The "timeout" error was numerically 60. Curiously, boards with RTL 8111GR chips did not produce these errors, but those with RTL 8111H chips did. Unfortunately, this chipset seems to be in a lot of newer motherboards.
I didn't use ktrace/kdump. The openmpi software returned the error presented by readv/writev. It sounds like the simplest solution at this point is to try non-Realtek pcie network cards. Any suggestions? How are Intel or Broadcom cards?
