This appears to be a duplicate of bug 1963712, although that bug is with a XPS 13 9310, rather then with a XPS 15 9500, but I'm pretty sure that this is the same issue. Can you please try the following: 1. Reboot and run "dmesg --level=warn" to check that you're seeing this problem on every boot. If you are still seeing this problem then the "dmesg --level=warn" output should include a backtrace similar to the one from comment 0. 2. If you are still seeing this problem, please run: "sudo grubby --update-kernel=ALL --args=tpm_tis.interrupts=0"; and then reboot (first save any work you may have open). 3. After rebooting run "dmesg --level=warn" again and see the problem still persists. Please let us know if adding tpm_tis.interrupts=0 to the kernel commandline like this helps. *** This bug has been marked as a duplicate of bug 1963712 ***
