Public bug reported:
I first noticed this about three weeks ago while scrolling through a
large PDF file via rdesktop; finally located error messages in kern.log
today. Symptom is sudden loss of network connection. Both systems
involved must be shut down, allowed to cool for several minutes, then
re-booted, to restore network actions. The kern.log entry indicates
timeout during file-splice action but I have not found more detail than
that.
