This is 4.9-rc7 on Sun Ultra 20 (Opteron 175 on NVidia chipset PC with
NVidia ethernet).

BUG: sleeping function called from invalid context at kernel/irq/manage.c:110

Hmm. No changes in either forcedeth or in the synchronize_irq() debugging.

But none of this looks new. I don't see _anything_ in any of these
areas that has changed since 4.8.

Which is why I suspect you changed something in your setup wrt
netconsole or your kernel config?

No changes that I could see. Only answered oldconfig questions, diff 
below. /etc/default/grub is from May so not changed recently. Just 
verified that 4.8.0 dmesg did not contain these warnings.

Conf diff and current config are below:

nv_do_nic_poll() is simply buggy and needs a fix.

synchronize_irq() can sleep.
