This actually caused more problems. The "failed to IDENTIFY (I/O error,
err_mask=0x11)" was still printed, plus there was a 5 second delay for each
port on the PMP during each of the 3 attempts to read the drive. In the end,
neither of the two SSD drives I tried ended up working. Changing ssleep(5)
to msleep(5) didn't remove the IDENTIFY errors, but still allowed the drives
to work.
Is there anyway to control the length of the reset pulse? I've heard that
some of the SSD's require the reset pulse to be held longer than normal.
For sata_sil24, it's determined by the controller. Hmmm... Please wait
a bit, I have another thing to try.
