From mboxrd@z Thu Jan 1 00:00:00 1970 From: hch@lst.de (Christoph Hellwig) Date: Sun, 7 Feb 2016 10:22:41 +0100 Subject: complete boot failure in 4.5-rc1 caused by nvme: make SG_IO support optional In-Reply-To: <1454783624.2809.6.camel@HansenPartnership.com> References: <1454783624.2809.6.camel@HansenPartnership.com> Message-ID: <20160207092241.GA15331@lst.de> Keith said it should be on by default, and I promised him to change it once we run into problems, which I guess this counts as. But just curious: what distro are you using? Upstream systemd explicitly rejected using scsi_id for NVMe here: https://github.com/systemd/systemd/issues/1453 and all my test systems don't do this either.
