Yes, that's interesting. On the ISP1362, the H_SUSPEND line needs to be pulled up, with a low strobe to wake it up. We never wake it up with that pin, but the ohci-isp1362 drivers didn't seem to care. So, I ignored the error with the CLKRDY pin, but now I'm getting two problems: 1a. I'm getting failed memory checks 1b. I'm triggering the _WARN_ON statements regarding HCuPINT_EOT at the end of write_buffer (which I'm assuming is the cause of 1a) 2. I'm getting 'irq24: nobody cared', which I'm assuming is because the driver has enabled interrupts on the chip before the driver has actually requested the IRQ. (This may be caused by the above error) My guess is I'm having trouble with the new write_buffer / write_fifo (as it uses writesl / writesw instead of its own loop). I'm going to go on this assumption (and ignore CLKRDY completely), unless anyone else runs into this problem or has a good idea. Thanks again!
