For that I had to select SMP on this UP-PowerPC G4 machine. 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.
Meanwhile, I gave up on the git bisect, as I can hardly boot inbetween

Thanks,
Christian.
