** Description changed:
+ Like mentioned in bug #1266305 (and before in bug #1265309) the
+ following problem occured:
+
+ 1. 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)
- - SSD Samsung 840 EVO Pro (was changed, former Samsung 840 EVO)
+
+ 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
- BIOS Mode Compat 2 (Compat, PCI powermangement OFF), no additional kernel
boot parameters.
+
+ 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)
- Tried the following kernel boot parameters but DRDY, hard resetting link:
+ 4. Troubleshooting so far
+ ------------------------------------------------
+ 4.1. Kernel boot parameters:
+
libata.force=1:3.0G,2:1,5G libata.force=noncq
- WORKAROUND: 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.
+ -> not working. DRDY, hard restting link.
- Testing the standard trusty kernel (linux-image-generic) with all BIOS modes.
- Testing the latest mainline kernel with all BIOS modes.
+ 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!
