Sorry for the delay getting to this, took me a bit to get the hardware together.
NAK, this patch introduces a trace to my test machines when I run the ethtool diagnostic on an e100 port, the system will sometimes survive a bit after the trace, however if I try to run traffic across the interface after the trace the system panics and locks up with a kernel not syncing message. I do not have a capture of the lock up panic (I can probably get one via serial port or netconsole if really necessary.) The trace before the lock up panic is as follows:

Sorry for the delay getting to this, took me a bit to get the hardware together.
NAK, this patch introduces a trace to my test machines when I run the ethtool diagnostic on an e100 port, the system will sometimes survive a bit after the trace, however if I try to run traffic across the interface after the trace the system panics and locks up with a kernel not syncing message. I do not have a capture of the lock up panic (I can probably get one via serial port or netconsole if really necessary.) The trace before the lock up panic is as follows:
