More info and pointers to fix here: http://lkml.indiana.edu/hypermail/linux/kernel/0812.1/02305.html or http://lkml.indiana.edu/hypermail/linux/kernel/0812.1/02590.html Just apply the patch to lib/idr.c and things should be fine again (or wait for stable.10). GregKH is doing an amazing job and it's not his fault, but nevertheless the rate of changes to -stable has just totally spiralled out of control. -h
