Hi All,

I compiled the latest git kernel today. Unfortunately my Varisys Cyrus 
Plus board still doesn't boot with the latest git kernel.

After that I patched the kernel source code with the spinlock patch and 
compiled the kernel again. With the spinlock patch, the latest git 
kernel boots without any problems.

Please find attached the spinlock patch.

Cheers,
Christian

Without the patch, the latest git kernel doesn't boot on my Cyrus Plus 
board.

Hi All,

A little success. :-) I reverted the following files from the bad 
commit a8a217c22116eff6c120d753c9934089fb229af0 [1]:

arch/powerpc/include/asm/spinlock.h
kernel/locking/spinlock.c
include/linux/spinlock_up.h
include/linux/spinlock.h
include/linux/rwlock.h

After that I compiled the latest git kernel again. Then I was able to 
boot the latest git kernel on my Varisys Cyrus Plus board [2][3]. :-)

That means the bug is in one of these files.

Please help me to find the bug in these files above.

Thanks,
Christian
