Problems in fixup_device function

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

Specifically, what are you trying to do?  Are you modifying the data
in the platform device?

Cheers,

I am loading the mac address into the data of the platform device.
