A null pointer deference is occurring in dccp_v4_
[ 174.691794] Unable to handle kernel paging request for data at address 0x000002f4
This is an offset from the pointer in register GRP09, which is zero:
[ 174.695217] GPR08: c000001df14a0800 0000000000000000 c000001e3b60c400 0000000000000000
Looking at the object code, I believe this oops is because the control sockets have been cleared for some reason, although it's not obvious why.
