Errr ... yes. Appears to be "Problem with enbd 2.2.27" (took a while to
figure out that richard was using smp). The thread appears to conclude:

Or propagate it down by force. You just have to copy and paste the
module compile line with the changes you want added in. For me, the
module appears to be compiled by:

 cd /tmp; gcc -O2   -Wall -D_LARGEFILE64_SOURCE -D__KERNEL__ -DMODULE
 -DDEBUG=0 -I/var/home/oboe/ptb/lang/c/nbd/nbd-2.4.15/linux/include
 -DUNIX98_NR_MAJORS=UNIX98_PTY_MAJOR_COUNT  -c -o nbd.o
 /var/home/oboe/ptb/lang/c/nbd/nbd-2.4.15/linux/drivers/block/nbd.c

so add -D__SMP__ there.

I don't think 2.91 is approved for kernel compilation? 2.96 certainly
isn't. I use 2.7.2.3 or sometimes 2.8.1 (since I know what those two
mess up).
