My laptop (Dell Inspiron 15 3537) gives me machine check exceptions on resuming from suspend, only on kernels with version >=4.3 (Checked upto 4.10rc1). I have checked on both Arch Linux and Xubuntu 16.04. On running a kernel bisect, the relevant change seems to have been introduced in the commit f29a7aff4bd6 ("x86/mce: Avoid potential deadlock due to printk() in MCE context", 2015-08-12).

The decoded MCE is in an attachment.

I am not sure what other information is relevant here, so please feel free to ask for more.
