But compiling -rc5 (as the bug is strill present in -rc5) fails with: /usr/local/src/linux-2.6-git/arch/powerpc/kernel/crash.c: In function ‘default_machine_crash_shutdown’: /usr/local/src/linux-2.6-git/arch/powerpc/kernel/crash.c:349: error: implicit declaration of function ‘crash_kexec_wait_realmode’ make[2]: *** [arch/powerpc/kernel/crash.o] Error 1 make[1]: *** [arch/powerpc/kernel] Error 2 make: *** [sub-make] Error 2 Maybe I'll just disable kexec and see if TREE_RCU helps.
