I pulled the latest staging-next onto Linus' latest git tree and still
experience problems with the driver. It seems that the first attempt to
actually transmit results in the system locking hard. Once again, I am
attaching the output from running a netconsole (due to the box I'm on,
it's an attachment this time, sorry about that - don't trust evolution)
where the trace is basically the same as the original trace I posted.

NOTE: in both cases, the driver is loaded with "msglevel=2
phymsglevel=2" which (although not documented) suggests to enable
tracing, and does certainly yield more debugging output.

Jon.
