May/June, and then later September and October, and I do= n't see anyone to have created a PR. I think I got confused and dismayed i= n June, from reading back, and then never got to trying hard again. >=20 > The first report I see is from Kurt, http://lists.freebsd.org/pipermail= /freebsd-sparc64/2014-March/009261.html, so well over a year ago.

Hopefully, some of the searching through various revisi= ons of 10/stable I documented in the "FreeBSD 10-STABLE/sparc64 panic" thre= ad in May 2014 may help in the end, though. >=20 It's fine, it explains why I could not find one. Kurt, could you please create a PR and point me to the PR number so RE can put it on our watch list? Thanks.
