Dear all, it seems that the ahci drivers fails with the (apparently supported) MCP89 chipset on Macbookpro7,1 machines. Typical error messages are : [ 12.520091] ata2: COMRESET failed (errno=-16) [ 12.520102] ata1: COMRESET failed (errno=-16) [ 17.910090] ata2: link is slow to respond, please be patient (ready=0) [ 17.910095] ata1: link is slow to respond, please be patient (ready=0) [ 22.530090] ata2: COMRESET failed (errno=-16) [ 22.530097] ata1: COMRESET failed (errno=-16) [ 27.920090] ata1: link is slow to respond, please be patient (ready=0) [ 27.920094] ata2: link is slow to respond, please be patient (ready=0) [ 57.560090] ata1: COMRESET failed (errno=-16) [ 57.560095] ata1: limiting SATA link speed to 1.5 Gbps [ 57.560102] ata2: COMRESET failed (errno=-16) [ 57.560105] ata2: limiting SATA link speed to 1.5 Gbps [ 62.590090] ata1: COMRESET failed (errno=-16) [ 62.590094] ata1: reset failed, giving up [ 62.590105] ata2: COMRESET failed (errno=-16) [ 62.590108] ata2: reset failed, giving up Hence, no disk nor cdrom work on macbookpro7,1. Full dmesgs, etc. can be found at https://bugzilla.kernel.org/show_bug.cgi?id=15923 . I wonder if there may be any parameters to tune in kernel command line to overcome this issue? Or is this a strong issue with the current driver? I can provide supplementary debug messages if needed.
