 netxen_nic_pci_mem_access_direct

We should probably add a might_sleep() to ioremap() to prevent these
bugs in the future.

This bug is eight years old.  You can report it, but it's going to hard
to get anyone to fix it.  I sometimes ignore ancient bugs.  On the other
hand, netxen is fairly well supported so it doesn't hurt to try.

I try to report bugs as soon as they are introduced.  I report it to
the author and CC the relevant list.  If people don't respond to my
email after a month then I complain again.

regards,
dan carpenter
