Hi,
I took the latest tree from linux/kernel/git/galak/powerpc.git
(2.6.26-rc2), and the latest dtc from linux/kernel/git/galak/dtc.git.
After compiling, I am having couple of questions.
1) Doesn't the latest dtc support /memreserve/ on the top before or
after /dts-v1/? This used to work fine for previous compiler and this is
giving an error now.
2) When I compiled and started booting the new kernel, I am getting a
kernel crash (copy pasted below) in hash_page routine when it executes
the assembly instruction "lwarx r6,0,r8". Can some one throw light at
this?
