For example; Ksoftirqd/1 %42, kworker/1:0 %29, kworker/1:1 %28. I'm not an expert. nonetheless I tried to pick some error messegas to ease your work. ata1: ACP=C4=B0 set timing mode failed (status: 0x300b) ata3.00 : exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata3.00 : failed command :READ VER=C4=B0FY SECTOR(S) cmd: 40/00:01:00:00:00/00:00:00:00/e0 tag 0 res: 40/00:01:00:00:00/00:00:00:00/40 Emask:0x4 (timeout) pm_op():scsi_bus_resume_common+0x0/0x60 returns 134217730 PM: Device 2:0:0:0 failed to resume async:error 134217730 Other messages that I picked randomly... ata3: lost interrupt (Status 0x50) ACPI Exception: AE_AML_PACKAGE_LIMIT, Index (0x00000000FFFFFFFF) is beyond end of object (20110623/exoparg2-418) ACPI Error: Method parse/execution failed [\_SB_.PCI0.IDEC.IDE0._STM] (= Node ffff8800ba233b40), AE_AML_PACKAGE_LIMIT (20110623/psparse-536) ata3.00: status: { DRDY } ata3: soft resetting link ata3.00: configured for UDMA/133 ata3.00: device reported invalid CHS sector 0 ata3: EH complete sd 2:0:0:0: [sda] START_STOP FAILED sd 2:0:0:0: [sda] Result: hostbyte=3DDID_OK driverbyte=3DDRIVER_SENSE sd 2:0:0:0: [sda] Sense Key : Aborted Command [current] [descriptor] sd 2:0:0:0: [sda] Add.
