We have started seeing a rash of errors on some of our Linux virtual servers. The message we see on the virtual machine console is "Unknown program exception: 0028 [#1] SMP". It appears to only affect servers that were recently patched to kernel level "2.6.32-696.23.1.el6.s390x #1 SMP Sat Feb 10 11:11:31 EST 2018". It does not affect all of our servers that were recently patched. I suspect that it might be related to patches related to Spectre. I did a google search and did not get any hits on the message. I expect our Linux team will contact Red Hat support.
Has anyone else seen this?
