My OS hangs during starting resume. (Suspend works fine.) System can be rebooted only with CTRL + ALT + Print Screen + REISUB.
I have tried downgrade kernel. It does not work(
"mce: [Hardware Error]: Machine check events logged" appears in syslog. What should I do?).
Updated:
Resume for virtual console does not work too(
Unable to resume after suspend).
OS Information:
Description: Ubuntu 15.10 wily
Kernel: x86_64 Linux 4.2.0-27-generic
Question: How to resolve the issue? Any suggestions. How to prepare a well bug for developers?
