Bug Description
Overnight I had 2 of 12 16.04 servers brick with the 108 kernel. They also do not work with 109. They work fine with 104. The other 10 worked fine on both 108 and 109.
All are hosted on VMWARE. The two broken ones stop at the same place. I was able to go back to the 104 kernel to get them working and pin the kernel version.
Just for fun, I set zswap.enabled=0 and they both crashed with kthread starved for jiffies. They are both multi-processor with lots of ram and disk.
I have a task from the Ubuntu Kernel team to try this with 'nopti'. I'll report back.

booting on 109 with nopti works! Good call Leann.
