I can post a log, but:
Interrupts are occuring, and being trapped.
The following code in the driver just seems to always return
IRQ_NONE when called from an interrupt.
int_status = c67x00_ll_hpi_status(c67x00);
if (!int_status)
return IRQ_NONE;
However, if I add a timer that just polls the interrupt handler, I
have the driver working (on the first port) but slowly.
