Hi,
since kernel version 4.5 my t5220 does not boot anymore, small logs
attached...
bisecting the problem points to commit:
1a40b95374f680625318ab61d81958e949e0afe3
or
1a40b95 (sparc: Fix system call tracing register handling.)
I verified that reverting the above commit solves the kernel boot
problem on stable 4.5.2 and master of today.
Let me know what I can do to help tracking down that issue or if I'm
doing anything else stupid
