Analyze and fix the following issue in the Linux kernel code: ahci: use 0x80 as wait stat value instead of 0xff
Problem Details: Before hardreset, ahci initialized stat part of received FIS area to 0xff to wait for the first D2H Reg FIS which would change the value to device ready state. This used to work but now libata considers status value of 0xff as device not present making this wait prone to failure. This patch makes ahc...
