thedanyes, thank you for your comment. So your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into a Ubuntu repository kernel (not a mainline one) via: ubuntu-bug linux
For more on this, please read the official Ubuntu documentation: Ubuntu Bug Control and Ubuntu Bug Squad: https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue Ubuntu Kernel Team: https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Filing_Kernel_Bug_reports Ubuntu Community: https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette When opening up the new report, please feel free to subscribe me to it. Thank you for your understanding.

During boot I have to wait for 20 seconds due to the following scenario: Excerpt of dmesg | grep ata: [ 7.718628] ata1: link is slow to respond, please be patient (ready=0) [ 12.365148] ata1: COMRESET failed (errno=-16) [ 17.723437] ata1: link is slow to respond, please be patient (ready=0) [ 22.369960] ata1: COMRESET failed (errno=-16) [ 27.728248] ata1: link is slow to respond, please be patient (ready=0) [ 57.398789] ata1: COMRESET failed (errno=-16) [ 57.398800] ata1: limiting SATA link speed to 1.5 Gbps [ 57.718702] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) After that the Intel SSD is connected in limited SATA1 mode to the system. :-( The same SSD works on the same machine just fine under windows 7, thus I think one can exclude hardware issues here.

Please help, as I would like to decrease my boot time from now 1 Minute a bit further AND most important of course I want to use a SATA mode that is capable of deliver data as fast as the super expensive drive can do it also under Ubuntu!
