Bug #2355: panic: rtrequest1_msghandler: rtrequest table error was cpu4, err 17

I experimented with wlan and dhcp and had some trouble to get it to work.
To start from scratch, I've deleted the generated interface wlan0 after running /etc/rc.d/netif stop.
At some point after running /etc/rc.d/netif start again this panic occurs. This is reproducible.

A dump is available.

It will be helpful to have a dump.

I've uploaded the dump on leaf, ~jaydg/crash/2355.

I switched the main ethernet interface from bce0 to ix0:
ifconfig bce0 -alias xxx
ifconfig ix0 192.168.x.x/24

At this point, the default route was gone
As soon as I typed route add default to add it again, the system crashed

% Done changed from 0 to 10

I got the same sort of panic on a 24-threads xeon box:
rtrequest1_msghandler: rtrequest table error was cpu16, err 17

I have checked the jaydg's core, it is crashed on a 6 logic cpu box;
same as yours 24 logic cpu box, i.e. the cpu count is not aligned on
power of 2. Following commit should have fixed it:
271d38c464d5d4591bc37fb66189c6fbc2a6a5be

It could be cherry-picked to 3.0 release branch.

Best Regards,
sephe
