Subject: Re: How to set DPOFUA=0 ?
Date: Tue, 29 Dec 2015 12:30:28 +0100 [thread overview]
Message-ID: <n5tqsl$5eg$2@ger.gmane.org> (raw)
In-Reply-To: <n5kqb4$k8n$1@ger.gmane.org>
Solved:
By installing a the latest kernel and headers from Debian backports solved the
problem:
apt-get -t jessie-backports install linux-image-amd64 linux-headers-amd64
Info about backports configuration:
http://backports.debian.org/Instructions/
# uname -a
Linux panther 4.2.0-0.bpo.1-amd64 #1 SMP Debian 4.2.6-3~bpo8+2 (2015-12-14)
x86_64 GNU/Linux
After this nigtmare-ish experience I would suggest the debian maintainers
to trash the default jessie kernel 3.16 and replace it with the above
4.2 kernel; otherwise unexperienced users will wonder why their new SSD etc.
isn't working in debian/ubuntu & co., as happened to me... :-(
