Re: Workstation 23 (Beta) locking up

[Sanne Grinovero]

Thanks for all suggestions, I tried to apply them and this is what I got.
While I don't use the Android Studio I did often use Eclipse and other
Java heavy processes in the past days (I'm a Java developer playing
with big data, so the heavy apps idea sounded interesting).

So today I've been leaving the laptop on, but without using it at all:
just logged in Gnome 3, no apps running.

After some hours it crashed, and (after waiting a bit and then
rebooting), this is the output of `journalctl -b -1` after restarting
it:

[repeated over and over for several pages]

I then repeated the cycle, but with an open SSH terminal from my other
workstation (Fedora 22).
Again after some hours the system seemed locked up again. But the SSH
terminal was not disconnected!
I eventually got the "Broken Pipe"

Yes it's an Intel one, and yes I'm using a dock but it's only to get
it charged conveniently and connect to other perks - such as wired
network and input devices - but the dock has no monitor attached.

I've had the lockups happen frequently when travelling; been away for
2 weeks now: that implies no dock at all for many days, and even with
several reboots between the last time it was in the dock (obviously,
because of the issue itself).

Thanks,

Workstation 23 (Beta) locking up

[Sanne Grinovero]

[re-sending after being pointed to the right mailing list]

Hi all,
I was brave enough to upgrade my primary work laptop - a Lenovo laptop
T440s - from Fedora 22 (workstation) to the Beta of version 23.

The upgrade was smooth, Gnome 3 is working great, and it's all looking
gorgeous but the machine occasionally seems to "freeze" and I have to
long-press the power button to force a shut down as it won't react to
any other key combination I tried (from ctrl-alt-del to
ctrl-alt-F1..F9, ctrl-alt-backspace).

Kernel version is  4.2.1-300.fc23.x86_64 (not tainted nor customized).

The boot command line is the "vanilla" one:
 BOOT_IMAGE=/vmlinuz-4.2.1-300.fc23.x86_64
root=UUID=f12bc342-dcf1-4c72-815f-4d3c0475a9f0 ro
rootflags=subvol=root vconsole.font=latarcyrheb-sun16 rhgb quiet

Is there anything I can do to help getting this fixed?

I guess a good start would be to report it on some issue tracker, but
I'm not sure which one, or which component: I probably need some help
to narrow it done somewhat?

Thanks,
Sanne
