I can use the system without notable problem (though I have not run any performance tests yet), however the kernel frequently (every few seconds) writes the following error messages to /var/log/syslog: ..... kernel: [ 1814.181384] ata4: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen kernel: [ 1814.181395] ata4: irq_stat 0x00000040, connection status changed kernel: [ 1814.181402] ata4: SError: { CommWake DevExch } kernel: [ 1814.181416] ata4: hard resetting link kernel: [ 1814.903561] ata4: SATA link down (SStatus 0 SControl 300) kernel: [ 1814.919517] ata4: EH complete kernel: [ 1819.682620] ata4: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen kernel: [ 1819.682631] ata4: irq_stat 0x00000040, connection status changed kernel: [ 1819.682637] ata4: SError: { CommWake DevExch } kernel: [ 1819.682651] ata4: hard resetting link kernel: [ 1820.403106] ata4: SATA link down (SStatus 0 SControl 300) kernel: [ 1820.419060] ata4: EH complete kernel: [ 1825.277218] ata4: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen kernel: [ 1825.277228] ata4: irq_stat 0x00000040, connection status changed kernel: [ 1825.277234] ata4: SError: { DevExch } kernel: [ 1825.277246] ata4: limiting SATA link speed to 1.5 Gbps kernel: [ 1825.277253] ata4: hard resetting link kernel: [ 1825.998398] ata4: SATA link down (SStatus 0 SControl 310) kernel: [ 1826.014355] ata4: EH complete .... Again, the system is brand-new and hence I guess that this is no hardware problem. Searching the web I found that someone else with a T520 has a similar problem: http://comments.gmane.org/gmane.linux.kernel/1207661 Thank you very much in advance!
