Samsung 840 Pro 512GB not recognized

[hyper_ch]

In order to get newer systemd version I installed 15.10.

However the partition manager (using the server image) did not recognize the Samsung 840 Pro SSD. I was forced to go back and install 15.04, then upgrade to 15.10 and that worked without issues.

Changing to a different tty and doing checking /dev/disk/by-id also shows no sign of the Sasmungs 840 Pro.

The server image does not use ubiquity. Does the drive show up in /dev or cat /proc/partitions?

[hyper_ch (bugs-launchpad-net-roleplayer)]

no, it doesn't show up there.

[Phillip Susi (psusi)]

Can you get a copy of /var/log/kern.log at this point?

[hyper_ch (bugs-launchpad-net-roleplayer)]

I'd need to redownload Wily, start installation and test it then. However the main issue would be:

How would I save the kern.log?

[hyper_ch (bugs-launchpad-net-roleplayer)]

Couldn't find kern.log but tried to find other stuff.

These errors seem to indicate that either the drive or sata controller are defective:

Are you sure it works when you upgrade? Are you booting with any special kernel command line arguments? cat /proc/cmdline please.

[hyper_ch (bugs-launchpad-net-roleplayer)]

Well, I did install 15.04 without troubles and upgraded to 15.10 and it works without troubles.

No special kernel command line arguments. Whatever comes as default for the installer and then ubuntu itself.

[Phillip Susi (psusi)]

Can you attach a syslog from this upgraded and working boot for comparison?

[hyper_ch (bugs-launchpad-net-roleplayer)]

Here's the syslog

[Phillip Susi (psusi)]

That is very, very strange. I can't see how any of these could possibly make a difference, but I did notice that your working boot uses these three command line arguments:

pcie_aspm=force nomdmonddf nomdmonisw

You might try pressing F6 when booting the installer and add those arguments to the kernel command line ( before the -- ), and see if it changes things.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[hyper_ch (bugs-launchpad-net-roleplayer)]

Brad: what good is that log for? This happens during the installation.

[hyper_ch (bugs-launchpad-net-roleplayer)]

I just noticed that yesterday kernel 4.0.0-4 hit the repos

So today I made a new installer stick with current daily image and now it works fine. Both my installer problems are gone:

- ethernet card gets dhcp connection
- ssd is recognized in the partitioner

I tried first with those kernel boot params and then without. Result was the same.

Whatever it was, it didn't like 3.19 kernel for installation somehow.
