HELP!!! BUG: scheduling while atomic"
Linux ver: 18.104.22.168(i686 GNU/Linux)
I have modified kernel space IP stack code to install a route in the IP routing table under certain condtions. For example, when a telnet packet is received I install a route. I done this in kernel IP input processing code by calling API, inet_ioctl to install the route.
Most of the time the (above changed) code works fine and installs route in the routing table successfully. Occasionally, I see the kernel BUG message with following trace. Usually when I telnet continuously I see this more often.
