The perf hw \nbreakpoint fails and it result in call traces, which then causes\nthe system to reboot.\n\nThis bug is fixed by commit d89ba5353f301971dd7d2f9fdf25c4432728f38e which is\nin mainline as of v4.12-rc7. This commit was also cc'd to upstream stable, but\nZesty never recieved it because upstream 4.10 is EOL.\n\n\n== Fix ==\ncommit d89ba5353f301971dd7d2f9fdf25c4432728f38e\nAuthor: Naveen N. Rao \nDate: Wed Jun 14 00:12:00 2017 +0530\n\n powerpc/64s: Handle data breakpoints in Radix mode\n\n== Regression Potential ==\nSpecific to powerpc. Also, this commit was also cc'd to stable and accepted, so additional upstream review\nwas performed.\n\n== Test Case ==\nA test kernel was built with this patch and tested by the original bug reporter.\nThe bug reporter states the test kernel resolved the bug.\n\nNaveen N.
