Indeed, upgrading to kernel-2.6.11-1.1341_FC4 seems to have solved
this aspect of the problem.  Thanks very much.

Meanwhile, the other error messages with regard to networking remain:
i.e. NETDEV WATCHDOG: eth0: transmit timed out.  I've attached below
the diagnostics run under the new kernel.  I'd like to chase down this
problem, but I'm unsure from what angle to attack.

Best wishes,
