My Dell 755 PC with 16.04 (and a dual-boot of Windows 10) has a problem. It started right after some updates that required a reboot to complete.

My question is, is this a reportable bug, considering the symptoms below? If so what should be in the report?

Of course, advice about diagnosing and fixing my system also is welcome.

Symptoms:

• If I boot into the default Ubuntu option of the GRUB menu, it hangs a long time after checking or fixing lost inodes on sda3, and eventually reboots into emergency mode.


• If I boot into the "upstart" option in the "advanced" submenu in GRUB, it boots fine.


• The one time that I did a journalctl -xb during the problem, it showed that my system disk (sda3) had timed out. After a successful boot, the command shows nothing.


• The PC boots Windows 10 OK. (It's dual boot). The PC boots a live DVD of 16.04 fine and the drives can be mounted r/w without errors.


• GSmartControl shows no new errors, and runs tests with no errors.

Diagnostic/config info, per first comment:

sda3, sda5, and sda6 are all Logical partitions on the same Primary partition, which begins at roughly the "middle" of the hard drive, after the Windows 10 partition.

I have no reason to think the drive is failing except the timeout in systemd. Once it boots, in either Ubuntu or Win10, there are no hardware errors or odd symptoms.
