Hi There are unhandled events when undocking TP X230 (2325-7BG) from the Ultrabase Series 3 docking, P/N 0B67692. Below I include the output to /var/log/messages when disconnecting and connecting the docking. Thank you for your time. §:-) Christer When pressing the disconnect button on the docking: May 8 11:26:44 localhost kernel: ACPI: \_SB_.GDCK - undocking May 8 11:26:44 localhost kernel: ata2: exception Emask 0x10 SAct 0x0 SErr 0x4090000 action 0xe frozen May 8 11:26:44 localhost kernel: ata2: irq_stat 0x00400040, connection status changed May 8 11:26:44 localhost kernel: ata2: SError: { PHYRdyChg 10B8B DevExch } May 8 11:26:44 localhost kernel: ata2: hard resetting link May 8 11:26:44 localhost kernel: usb 2-1.3: USB disconnect, device number 4 May 8 11:26:45 localhost kernel: ata2: SATA link down (SStatus 0 SControl 300) May 8 11:26:50 localhost kernel: ata2: hard resetting link May 8 11:26:50 localhost kernel: ata2: SATA link down (SStatus 0 SControl 300) May 8 11:26:50 localhost kernel: ata2: limiting SATA link speed to 1.5 Gbps May 8 11:26:55 localhost kernel: ata2: hard resetting link May 8 11:26:55 localhost kernel: ata2: SATA link down (SStatus 0 SControl 310) May 8 11:26:55 localhost kernel: ata2.00: disabled May 8 11:26:55 localhost kernel: ata2: EH complete May 8 11:26:55 localhost kernel: ata2.00: detaching (SCSI 1:0:0:0) When undocking: May 8 11:27:19 localhost kernel: thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received May 8 11:27:19 localhost kernel: thinkpad_acpi: unhandled HKEY event 0x6040 May 8 11:27:19 localhost kernel: thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx May 8 11:27:19 localhost kernel: thinkpad_acpi: unhandled HKEY event 0x4011 May 8 11:27:19 localhost kernel: thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx May 8 11:27:19 localhost kernel: thinkpad_acpi: EC reports that Thermal Table has changed May 8 11:27:19 localhost kernel: ACPI: \_SB_.GDCK - undocking When docking: May 8 11:19:54 localhost kernel: ata2: exception Emask 0x10 SAct 0x0 SErr 0x4050002 action 0xe frozen May 8 11:19:54 localhost kernel: ata2: irq_stat 0x00000040, connection status changed May 8 11:19:54 localhost kernel: ata2: SError: { RecovComm PHYRdyChg CommWake DevExch } May 8 11:19:54 localhost kernel: ata2: hard resetting link May 8 11:19:55 localhost kernel: ACPI: \_SB_.PCI0.SAT1.PRT1 - docking May 8 11:19:55 localhost kernel: ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) May 8 11:19:55 localhost kernel: ata2.00: ATAPI: HL-DT-ST DVDRAM GU40N, QX23, max UDMA/133, ATAPI AN May 8 11:19:55 localhost kernel: ata2.00: configured for UDMA/133 May 8 11:19:55 localhost kernel: ata2: EH complete May 8 11:19:55 localhost kernel: scsi 1:0:0:0: CD-ROM HL-DT-ST DVDRAM GU40N QX23 PQ: 0 ANSI: 5 May 8 11:19:55 localhost kernel: sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray May 8 11:19:55 localhost kernel: sr 1:0:0:0: Attached scsi generic sg1 type 5 May 8 11:20:06 localhost kernel: sr 1:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE May 8 11:20:06 localhost kernel: sr 1:0:0:0: [sr0] Sense Key : Illegal Request [current] May 8 11:20:06 localhost kernel: sr 1:0:0:0: [sr0] Add.
