"The new request for comments is from Collabora's Muhammad Anjum. Collabora does a lot of FOSS development, although its work on LibreOffice may be the most visible. (That may even speed up, as earlier this year, it merged with Allotropia, the company working on a WASM version of LibreOffice.)"
"Hibernation problems can potentially be severe, causing data loss. For instance, some machines hibernate successfully, and then resume again successfully - but on waking, the keyboard and mouse may not work, leaving you locked out and unable to cleanly save your work. That's why some distros leave it off by default - anything else risks data loss. As such, if you enable it, you will probably want to try it out repeatedly, so being able to cancel the process sounds good to us."
"We strongly suspect that people would find hibernation more reliable if they remembered to update their system firmware, but sadly, few bother to do this. These days, there's the very helpful fwupd toolkit, but this too has a snag - for the system or motherboard firmware, this requires UEFI boot mode. It also needs a large ESP, and we've seen it fail when there's not enough space. This means that fwupd is less help on the older machines, which arguably need it most."
A new Linux kernel patch adds a mechanism to cancel hibernation by pressing the power button. Hibernation can take around twenty seconds on some machines and can be unreliable. Hibernation failures can cause data loss and can leave users locked out if input devices fail on resume. Firmware updates can improve hibernation reliability, but few users update their firmware. The fwupd toolkit can update firmware but requires UEFI boot mode and a sufficiently large ESP, limiting usefulness on older machines. Hibernation support remains a fragile and somewhat neglected area of Linux maintenance.
