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
