Hi Jeff,
this is a story regarding tulip-driver in a two separate cards-setup
where the driver thinks it is a multiple board setup, but the
eeprom-values do not back this theory. This seems the reason, why
last_ee_data turns out as NULL and its members get references later
on, which obviously breaks.
I fixed this with the patch on the very end of this, but am not 100%
sure if this is valid and does not break other setups.
Can you comment/verify/submit the bugfix-patch to marcelo and L for
inclusion?
Thanks,
Stephan
