With your patch I am still seeing an instant oops when running top(1):

connect(6, {sin_family=AF_UNIX, path="/var/run/.nscd_socket"}, 110) = -1 ENOENT (No such file or directory)
close(6)                                = 0
open("/etc/group", O_RDONLY)            = 6
fcntl64(0x6, 0x1, 0, 0x1)               = 0

The oops isn't very informative.  EIP is 0x00000000, call trace
is just "scheduling_functions_start_here+0x3dd/0x4a8"
