Public bug reported:
Upgrading to hwe-16.04 (i.e. from 4.4.0-116-generic to 4.13.0-37-generic,
amd64) has broken suspend to disk on my machine.
Suspend works fine, hibernation file is written to disk and system is powered
off.
During resume kernel is started and and the hibernation file is loaded.
Immediately after 100% screen is blanked, fans are still running but no SSH
possible, NumLock on keyboard is not working. So machine seems dead.
That happens for every suspend.
I could not read any error message before screen is blanked.
No messages from suspend found in syslog or kernel.log.
I tried to make it more verbose with "initcall_debug no_console_suspend
ignore_loglevel", but I have not managed to make messages persistent till next
boot.
