Now, in the logs, I see a bunch of Jul 26 11:01:51 <workstation> pkexec[29723]: <username>: Executing command [USER=root] [TTY=unknown] [CWD=/home/<username>] [COMMAND=/usr/libexec/gsd-backlight-helper --set-brightness 89] What little I can find sounds as though acpi_als is for a device that's checking the ambient light... NOT for a real monitor on a workstation. The other thing is that she says she's got screensaver set for five minutes, but it seem to come up much sooner, and then we've got this issue. There were no clues in journalctl, or /var/l...

The error message I get is: Kernel panic - not syncing: include/linux/smp_lock.h:25 spin_unlock(kernel/sched.c:c035) not locked The boot messages before this point are mainly to do with acpi including: acpi_ps_parse_anl acpi_?s_one_complete ... acpi_early_init start_kernel Kernel panic .... At a guess, I tried starting the installer with the options: linux text acpi=off noprobe I am not really clear on what part of the boot process is failing so I tried a number of random boot options including ap...

The FBIOPUT_CON2FBMAP ioctl takes a console_lock(). When this is called while nouveau was runtime suspended, a deadlock would occur due to nouveau_fbcon_set_suspend also trying to obtain console_lock(). Fix this by delaying the drm_fb_helper_set_suspend call. Based on the i915 code (which was done for performance reasons though). Cc: Chris Wilson <chris at chris-wilson.co.uk> Cc: Daniel
