It is causing occasional boot crashes, caused by certain linker versions (GNU ld version 2.18.50.0.6-2 20080403) messing up: 82dcc000 D __per_cpu_load c16e6000 A __per_cpu_load_abs The __per_cpu_load value is out of whack. Hpa noticed the following detail: * (gdb) p/x -(0xc16e6000-0x82dcc000) * $2 = 0xc16e6000 * I.e. one is the other << 1 The two symbols should be equal.
