For your information, a friend of mine has the exact same SATA-card & hard-disk combination (Promise Sata300TX4 + 2*Seagate 7200.10) with Intel P4 & 875P chipset and gets similar error messages every once in a while when there is above average disk I/O in the system (for example raid-recheck). ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata4.00: cmd 25/00:00:bf:0f:87/00:04:05:00:00/e0 tag 0 cdb 0x0 data 524288 in res 50/00:00:be:13:87/00:00:05:00:00/e0 Emask 0x1 (device error) So at least it doesn't seem like my hard-disks or SATA-card are faulty/broken.
