Hi, alias -g hib='sudo s2ram --force --vbe_post' worked fine for me for years.
This year on fresh OS / new live flash memory stick I got: "I/O Device Error" and then a "read only mode" after "Waking up". Got this issue on 2 laptops almost at same time. Any advices how to fix it on Jessie ? Confs: Debian GNU/Linux 8 uswsusp 1.0+20120915-6 No SystemD -- Best regards, Nikolay Mashkov
