Created attachment 849559 [details] dmesg after lockup
I've just experienced a kernel stall on my Lenovo Thinkpad X270, attached.
At this point I have no idea how to proceed, and no, I cannot reproduce the hang at will.
The information is very limited. I understand there is no more stack trace, and I can only guess what happened.
I see one fix is about using an encrypted swap device, do you encrypt the swap partition ?
I see some suspicious and necessary fixes from dm-crypt deadlocking. commit 528b16bfc3ae ("dm crypt: Avoid percpu_counter spinlock contention in crypt_page_alloc()") commit c87a95dc28b1 ("dm crypt: defer decryption to a tasklet if interrupts disabled") commit a666e5c05e7c ("dm: fix deadlock when swapping to encrypted device") Let me try to do the backport.
