Can someone familiar with how the AHCI driver works confirm that data overruns on a SATA link can cause the driver to down-shift the SATA speed 6->3->1.5 Gbits/sec. I don't see any kprintf's but I notice that a high speed SSD acting as if the SATA were running at 1.5 Gbits/sec.
This looks like it could be a bug. I can see down-shifting as a response to noise on the SATA link, but downshifting for data overrun reasons is only going to make the problem worse. -wolfgang -- g+: https://plus.google.com/114566345864337108516/about -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
