[SOLVED]Dell XPS 13: root partition mounted read-only resuming/suspend
Hi,
Since the latest kernel update to 4.13.4, my laptop has the root partition immediately mounted as read-only after suspend and I cannot remount it rw since sudo (or just anything) throws errors as well. Anyone experiencing this lately? I can only reboot the system using Alt+SysRq+reisub...
The problem does not occur with the LTS kernel, so it must be a regression in 4.13.4.
When resuming from suspend with the console open, I can see a stream of error messages running over the screen for a few seconds. This is the final screen:
.
Edit: Partial Solution: Add intel_iommu=off to your kernel boot parameters.

Various screen lockups and also resume from suspend started failing after the kernel 4.12->4.13 kernel update on my XPS 13 9343. Adding intel_iommu=off boot parameter fixed all problems. See the plethora of other posts around here about the issue.

I just upgraded to 4.13.5, added intel_iommu=off to my kernel parameters and the problem is indeed solved. Thank you.
BTW, my lts kernel is loaded with intel_iommu=igfx_off, which seems to be sufficient, at least for 4.9.

Hi

No longer needed with kernel 4.13.5
A+
