I’ve added some code to virtex_device_fixup and am seeing some strange side affects.  I’ve added code to read from an iic device and populate the mac address including ioremap.  The code works fine, but the side affects are not fine.

Anyone have any experience here?

I see the loops_per_jiffy getting hosed like there is some bad code, but I can’t track it down.  It moves around badly, like it can come and go with printk additions or deletions.

I don’t know enough about the stack and Linux to know if there could be a problem there.

Thanks,

John
