zardoz, Vuen, since there is so much going on here (AHCI, no AHCI, kernel versions, etc.), I'm going to mark this as "rejected" to close it. If you could open new bug reports for the current specific behavior, that would be fantastic. If it looks like AHCI SATA is the culprit, we'll come update this one appropriately.
In the new bug reports, please be sure to include the following: Include in the report the output of uname -a Attach to the report the output of the following commands (one attachment per command please, it's not necessary to make one big attachment or to compress the attachments): sudo lspci -vv sudo lspci -vvn sudo dmidecode Please be sure to use sudo, root privileges are required to obtain the needed information. Finally, please do the following sequence: 1. Boot 2. Hibernate 3. Attempt to resume 4. Reboot (however you need to) 5. Attach /var/log/kern.0.log to the new bug report: It will cover steps 1-3 and show us what was happening during that failed sequence.
