Title:
Problems with shut down and boot (Lenovo T450s)
Status in linux package in Ubuntu:
Expired
Bug description:
My Lenovo T450s under Ubuntu 15.10 does not poweroff normally.
Instead, it hangs on "Reached target shutdown". (See image)
Along the way, I believe there is briefly a full page of
"drm:gen8_irq_handler [i915] *ERROR* The master control interrupt lied (SDE)!"
messages.
If I leave it there for a long time (> 10 minutes?) it does/may
actually turn off without me forcing it off, but this makes no
difference to the subsequent behaviour. Moreover, if I press Ctrl-
Alt-Del fast, many times, I get the "Rebooting immediately" message,
but it doesn't.
When I try to boot, I experience the following. It requires at least
two reboots to be able to log in:
On the first boot, the Grub page is skipped, and it hangs on the Ubuntu logo
with moving dots.
Eventually, I reboot it.
The second time (this is all reproducible), it boots but very slowly. It
stalls at "britty.service" and eventually gives me a message
about dev-disk-by , where it waits for 90 seconds before booting.
After that, things proceed to a normal login screen. Behaviour after that is
sometimes normal.
This is a 1 month-old computer.
