So we loose the opportunity to retrieve the content of the registers by the time of the failure.<br/> Having BUG instead of panic sends an invalid instruction raising an interrupt and then dump all registers, giving a real advantage of not losing this critical information.</p> <p>This is why we propose to add a new 'use_bug_instead_of_panic' entry under /proc/sys/lnet, that is complementary with panic_on_lbug. To use it, panic_on_lbug must be set, and in that case we replace panic with BUG.</p> <p>I will attach a patch to address this code change.</p> <p>Sebastien.</p> LU-5174
