When copying large files, there happen to be timeouts like: ---SCHNIPP--- ahcich2: Timeout on slot 18 port 0 ahcich2: is 00000000 cs 00040000 ss 00000000 rs 00040000 tfd c0 serr 00000000 cmd 0000d217 ahcich2: Timeout on slot 13 port 0 ahcich2: is 00000000 cs 00002000 ss 00000000 rs 00002000 tfd c0 serr 00000000 cmd 0000cd17 ahcich2: Timeout on slot 3 port 0 ahcich2: is 00000000 cs 00000008 ss 00000000 rs 00000008 tfd c0 serr 00000000 cmd 0000c317 ahcich2: Timeout on slot 11 port 0 ahcich2: is 00000000 cs 00000800 ss 00000000 rs 00000800 tfd c0 serr 00000000 cmd 0000cb17 ---schnapp--- and the system becomes that slow, that starting an xterm takes up to e.g. one minute, and some ``ls'' about 40 seconds (the actual amount of time varies). Some further information: ---SCHNIPP--- dmesg|grep -i ahci ahci0: <Intel Cougar Point AHCI SATA controller> port 0xf070-0xf077,0xf060-0xf063,0xf050-0xf057,0xf040-0xf043,0xf020-0xf03f mem 0xfa305000-0xfa3057ff irq 20 at device 31.2 on pci0 ahci0: AHCI v1.30 with 6 6Gbps ports, Port Multiplier not supported ahcich0: <AHCI channel> at channel 0 on ahci0 ahcich1: <AHCI channel> at channel 1 on ahci0 ahcich2: <AHCI channel> at channel 4 on ahci0 ahcich3: <AHCI channel> at channel 5 on ahci0 ada0 at ahcich0 bus 0 scbus3 target 0 lun 0 ada1 at ahcich1 bus 0 scbus4 target 0 lun 0 ada2 at ahcich2 bus 0 scbus5 target 0 lun 0 cd0 at ahcich3 bus 0 scbus6 target 0 lun 0 ---schnapp--- It is an ``ASUS P8H67-M Rev.3.0 (New H67 B3 Revision)'' motherboard. May be these information help. Greetings, Kalten >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
