I rebooted with the paramters of comment #33 ( https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1269777/comments/33). PCIE powermanagement is DISABLED in the BIOS.
Then I did the undocking operation: It is working like expected without any problem!

System -------------------------- - Ubuntu 14 04 LTS (acutal development branch) - linux-image-generic v. 3.13.x, mainline kernel 3.13.x (first testing the standard kernel), last 3.12 mainline kernel - lvm with trim support (batched discard) - tlp (currently disabled for testing purpose) 2. Hardware: --------------------------- - Lenovo W510 i7 quad core - SSD Samsung 840 EVO Pro (former Samsung 840 EVO, was changed in hope that the problem disapears) - nvidia graphics BIOS (defaults F9) and: - BIOS Mode Standard 1: SATA: AHCI, POWER: pci and pcie power management AUTOMATIC - BIOS Mode Standard 2: SATA: AHCI, POWER: pci and pcie power management OFF - BIOS Mode Compat 1: SATA: Compatability Mode, POWER: pci and pcie power management AUTOMATIC - BIOS Mode Compat 2: SATA: Compatability Mode, POWER: pci and pcie power management OFF 3. Problem descripton ----------------------------------------------- The SSD randomly freezes with the following errors: ata1: EH complete ata1: limiting SATA link speed to 1.5 Gbps ata1.00: exception Emask 0x52 SAct 0x1 SErr 0x1a80d00 action 0x6 frozen ata1.00: irq_stat 0x08000000, interface fatal error ata1: SError: { UnrecovData Proto HostInt 10B8B BadCRC LinkSeq TrStaTrns } ata1.00: failed command: READ FPDMA QUEUED ata1.00: cmd 60/08:00:d8:b9:27/00:00:05:00:00/40 tag 0 ncq 4096 in ata1.00: status: { DRDY } ata1: hard resetting link ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Probably affect other Thinkpad models too: - http://www.sevenforums.com/bsod-help-support/309288-bsod-after-few-minutes-5-55-minutes-samsung-ssd-840-evo.html - [GERMAN] http://thinkpad-forum.de/threads/168841-Freezes-nach-Einbau-einer-neuen-SSD?p=1698795#post1698795 - http://www.howtoeverything.net/linux/hardware/ubuntu-freeze-issue-after-ssd-upgrade 4. Troubleshooting so far ------------------------------------------------ 4.1. Kernel boot parameters: libata.force=1:3.0G,2:1,5G libata.force=noncq -> not working. DRDY, hard restting link. 4.2. BIOS Mode Compat 2 (Compat, PCI powermangement OFF), no additional kernel boot parameters. System ran with standard generic kernel 3.13.x for over 12 hours usage without any problems. I did some suspend/ resume cycles: no problems. 5. Further testing: -------------------------------------------------------- Testing scenarios will be applied in the follwowing structure (if necessary) 5.1 Testing the standard trusty kernel (linux-image-generic) 5.1.1. with all BIOS modes. 5.1.2. eventually kernel boot parameters 5.2. Testing the latest mainline kernel with all BIOS modes. 5.2.1. with all BIOS modes. 5.2.2. eventually kernel boot parameters This could take a few days, so be patient. Keeping fingers crossed ;-) P.S-.: Thanks a lot for Christopher M. Penalver for his excellent assistance so far! ###################################################################### Wed, 15 Jan 2014 18:00:00 +0100 - installed mainline kernel 3.13.0-031300rc8-generic - BIOS: SATA: Compatibility, POWER: pci / pcie power management OFF (!) - no tlp No problems until the next day (switched POWER management for pci and pcie on) ###################################################################### Thu, 16 Jan 2014 13:18:45 +0100 - installed linux-image-generic -> 3.13.0-3-generic - BIOS: SATA: AHCI, POWER: pci/pcie power management AUTOMATIC - Reboot with new standard kernel - no tlp yet! ###################################################################### ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-generic 3.13.0.3.6 ProcVersionSignature: Ubuntu 3.13.0-3.18-generic 3.13.0-rc8 Uname: Linux 3.13.0-3-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.13.1-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: apos 3069 F.... pulseaudio /dev/snd/controlC0: apos 3069 F.... pulseaudio CurrentDesktop: Unity Date: Thu Jan 16 12:35:13 2014 HibernationDevice: RESUME=UUID=7290992b-11df-4d5c-a9bc-579dafe5eb61 InstallationDate: Installed on 2014-01-08 (7 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20140105) MachineType: LENOVO 4391E46 ProcFB: ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.13.0-3-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash RelatedPackageVersions: linux-restricted-modules-3.13.0-3-generic N/A linux-backports-modules-3.13.0-3-generic N/A linux-firmware 1.121 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/03/2012 dmi.bios.vendor: LENOVO dmi.bios.version: 6NET84WW (1.45 ) dmi.board.name: 4391E46 dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr6NET84WW(1.45):bd10/03/2012:svnLENOVO:pn4391E46:pvrThinkPadW510:rvnLENOVO:rn4391E46:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 4391E46 dmi.product.version: ThinkPad W510 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1269777/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
