Subject: Oops running oprofile in 2.5.62
Date: Wed, 26 Feb 2003 22:29:43 -0800 [thread overview]
Message-ID: <3E5DB057.60503@us.ibm.com> (raw)
This happened while running dbench on 2.5.62. I haven't seen it before,
but I thought I'd report it anyway. I'm using the 0.5 version of the
userspace tools.
I'm pretty sure it happened on this line in oprofile_add_sample():
cpu_buf->buffer[cpu_buf->pos].eip = eip;
