Already changed the HBA and all cables. I still get this error in the log several times throughout the day. I do not recall getting that error prior to the upgrade to 6.9.2 RC2 What does it even mean? What is this task it tries to abort? *edit* Recently replaced the LSI 3008 with a LSI 2008 (including the cables), this error message still shows up.    Jan 18 07:23:17 NAS kernel: sd 3:0:4:0: attempting task abort!scmd(0x000000006d823564), outstanding for 15380 ms & timeout 150
