2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Reinhard Nissl commit ddccf307a3599e452804e228d8ed30fba578923e upstream. I increased the delay step by step until loading of mvsas reliably detected the drive 200 times in sequence. A much better approach would be to monitor the hardware for some flag which indicates that port detection has finished, but I do not have any hardware documentation.
