This is with the extra debug. Given that it is the timeout triggering,
only the sstatus is new.

ahci ata1: stat=d0, issuing COMRESET
ata1: started resetting...
ata1: end resetting, sstatus=00000113
ata1: recovering from error
ata1: status=0x01 { Error }
ata1: error=0x80 { Sector }
SCSI error : <0 0 0 0> return code = 0x8000002
sda: Current: sense key=0x3
    ASC=0x11 ASCQ=0x4
end_request: I/O error, dev sda, sector 66190875
Buffer I/O error on device sda2, logical block 8010795
lost page write due to I/O error on sda2
ata1: status=0x01 { Error }
ata1: error=0x80 { Sector }
SCSI error : <0 0 0 0> return code = 0x8000002
sda: Current: sense key=0x3
    ASC=0x11 ASCQ=0x4
end_request: I/O error, dev sda, sector 66159699
Buffer I/O error on device sda2, logical block 8006898
lost page write due to I/O error on sda2
