Cool, that helps a lot.
Do you have a copy of /usr/include/include/linux/scatterlist.h ?
Specifically I need line 65. Perhaps if you have the kernel source
or headers in /usr/src/....
I recall seeing something similar with OCF so if we can figure out exactly
which "BUG" caused the oops we may be able to resolve it for you :-)
Cheers,
