gnome-software crashes machine hard

[Thomas Jagoditsch]

gnome-software instantly crashes my machine hard reproducible, only forced power off possible.
mouse stuck, no num-lock, machine not pingable anymore.

as there is no crash report whatsoever generated i installed ssh on the machine and started "DISPLAY=:0 gnome-software --verbose" via ssh session, output attached.

tried to get additional information via recipes in https://help.ubuntu.com/community/DebuggingSystemCrash but no luck.
- Alt-SysRq does nothing at all
- linux-crashdump was successfully installed (checked via /proc/cmdline) but there is nothing in /var/crash after powercycle
- tracing the system logfiles via ssh revealed no further information

Could you add your syslog after getting the issue? Is your ssh session still active after getting the bug? Could be a kernel issue...

[Sebastien Bacher (seb128)]

Does moving /usr/lib/x86_64-linux-gnu/gs-plugins-11/libgs_plugin_fwupd.so away workaround the locking?

[Thomas Jagoditsch (tja)]

hi sebastien.

1.) ssh is dead as is the complete ip stack. see the syslog attachment.

2.) moving away /usr/lib/x86_64-linux-gnu/gs-plugins-11/libgs_plugin_fwupd.so will open gnome-software and is a workaround (btw. if one closes gnome-software via "X" it does close the window but the process lingers forever ...)

3.) after i saw that gnome-software had a problem with opening the USB mouse i tried to look for the device via lsusb -v ... where things got interesting.
lsusb -v works as user but as root it crashes the machine too - so this indeed looks like a kernel issue

(attaching some machine related info)

thanks, reassigning to the kernel thenb
