This is a note to let you know that I've just added the patch titled scsi: pm80xx: Fix for SATA device discovery to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: scsi-pm80xx-fix-for-sata-device-discovery.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c0229757bbd6a31218349c02d878a32eff769ad3 Author: peter chang <dpf@xxxxxxxxxx> Date: Thu Nov 14 15:38:58 2019 +0530 scsi: pm80xx: Fix for SATA device discovery [ Upstream commit ce21c63ee995b7a8b7b81245f2cee521f8c3c220 ] Driver was missing complete() call in mpi_sata_completion which result in SATA abort error handling timing out. That causes the device to be left in the in_recovery state so subsequent commands sent to the device fail and the OS removes access to it.
