Re: [PATCH net] netconsole: Check for carrier before calling netpoll_send_udp()

What if the carrier check passes, and then the chip reset starts on
another cpu?  You'll have the same problem.

Okay, let me see if I can come up with a better way to mitigate this.

We have seen a few crashes recently where a NIC is getting
reset for some reason and then the driver or another module calls
printk() which invokes netconsole. Netconsole then calls the
adapter specific poll routine via netpoll which crashes because
the adapter is resetting and its structures are being reinitialized.

This isn't a fix.

I'm not applying this, sorry.
