So I guess we go for the following. Is it verbose enough ?
It's got all of the details that seem to matter, thanks.
I'm letting people following this thread and the bug report know that I posted
the patch we discussed about here in the following thread:
https://lkml.org/lkml/2011/1/19/509
Feedback is welcome,
Hi Mathieu,
Thanks for this.
The good news is that I have a 2.6.37 kernel + your patches booting and
it has been running for about an hour on sparc64/Sun Fire V120. I did a
bit of poking around in /debug and turned on/off a bit of tracing and
nothing broke.
I did have a few problems applying your patch series. Your diffs have
semicolons at the end of a couple of the macros that don't appear in the
mainline 2.6.37. One was circa line 174 of include/linux/tracepoint.h
but I don't have the other to hand at the moment and I don't have much
time before I need to go out.
I'm also getting a lot of Kernel unaligned access errors from the
kernel. I don't know if they are related to this or not and this is the
first time that I personally have got 2.6.37 to boot on sparc64. The
messages that I am getting seem to be repeats of
[ 4376.807811] Kernel unaligned access at TPC[456e94]

I have to go out now but will be around later/over the weekend.
Regards
Richard
