Lenovo X301 hangs with AHCI Driver CMD TIMEOUT STS=d0<BSY>
I have a Lenovo X301 2776 LEG.
Trying to use the machine with the AHCI results in a hang for a while
then it can't mount the root FS as it can't access the disk.
The following message is displayed:
ahci0.1: CMD TIMEOUT state=5 slot=3
sactive=0000000 active=00000008 expired=00000000
ahci0.1: cmd 18: timeout
achi0.1: Warning, issuing CLO after timeout.
Prob0: ahci0:0:13:0) Unretryable error
