https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=198149 --- Comment #11 from John Baldwin <jhb@FreeBSD.org> --- Created attachment 156477 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=156477&action=edit first_hack.patch I tried this change which would cause iaf_read_pmc() to return -2 in this case instead of a large number. I added some additional debugging so I could verify this was being triggered in my testing. It did seem to make things last longer, but in at least one of my test runs I still saw pmcstat eventually stop getting samples. -- You are receiving this mail because: You are the assignee for the bug.
