Public bug reported:

Hi,

Any Ubuntu kernels since 4.10 hard freeze my X230 about 10 minutes after
the boot. I don't, unfortunately, have any logs, as usually the system
freezes before the logs sync to the disk. Immediately before the freeze,
iwlwifi disconnects and fails to connect back, spewing a few messages
about firmware errors, and then the whole system freezes.

The last kernel I can use successfully is Ubuntu 4.8 series.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: Incomplete

** Attachment added: "lspci-vnvn.log"

- Ubuntu kernels 4.10+ hard freeze on Thinkpad X230 about 10 after a boot.
+ Ubuntu kernels 4.10+ hard freeze on Thinkpad X230 about 10 minutes after a 
boot.
