I noticed that gcc 4.9.0 for sparc has landed on Debian unstable so I
gave it a try on V210. Does not boot with strange error about user
windows. This is reproducible. Since the same kernel comiled with gcc
4.6 booted fine, it's probably a gcc 4.9 difference.

Do you see the above when the kernel boots properly with the older gcc?
If not then I suggest to forward the bug report to the ext4 mailing list
(which I cannot remeber the address of - maybe fsdevel)

Yes, these lines are normal on most of my machines (compiling only ext4
and using it for ext2 and ext3 too if encountered).
In my reading of the dmesg and code, a fault in fault_in_user_windows is
causing the trouble when copy_to_user into init process fails.

I have done some more testing and digging.
About tests - 4.9 is problematic only on my UltraSparc IIIi machines
(V210 and V440). US I not tested yet, all US II variants work fine in my
servers. V480 with ful US III crashes with FATAL exception in different
point of startup so I do not know about it.

This is always the same.
Below are the disassemblies of fault_in_user_windows from 4.6.4 and
4.9.0.
