Bug ID: 363344
Summary: plasmashell fails to start when using kernel 4.5 and
higher. It works fine on kernel 4.4.
Product: plasmashell
Version: 5.6.4
Platform: Archlinux Packages
URL: https://bbs.archlinux.org/viewtopic.php?pid=1626335#p1
626335
OS: Linux
Status: RESOLVED
Severity: grave
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Status: RESOLVED
Resolution: INVALID
Messages appear while on kernel 4.5 when on command line:
systemd[1]: Journal service failed to start appear and kworker process is
blocked.
INFO: task kworker/u8:0:6 blocked for more than 120 seconds Tainted: G 0
4.5.2-1-ARCH #1 "echo bla bla bla" disables this message.
Sometimes it also I get this output as I am about to decrypt my home folder and
log in:
[18.783662] ata2.00: exception Emask 0x0 SAct 0x0 Serr 0x0 action 0x6 frozen

[18.783941] ata2.00: status: { DRDY }
********[21.687301] usb 1-3: device descriptor read/64, error -110
I never get these errors when I am in kernel 4.4.5-1
Reproducible: Always
Steps to Reproduce:
1. Upgrade from linux 4.4.5-1 to 4.5.2-1 in KDE Plasma 5.6.4
2. Restart machine
3. Boot normally
4. Blank screen (sometimes I can see my desktop wallpaper but rarely and
nothing else)
5. Restart machine
6. Boot in level 3 so you have command line instead of gui and these messages
appear sporadically from time to time.
Actual Results:
Blank screen and when on command line only the messages described in the
details appear.
Expected Results:
It should have shown the shell normally without the messages and everything
should have worked fine just like in kernel 4.4.5
The laptop runs hot as if trying to complete a heavy task. I think its caused
by the kworker not being able to run.
