I have an almost identical setup: SATA300 TX4 with 3 Samsung 400GB drives, and I get very similar errors. In 2.6.20 my card would soft restart all the way down to PIO mode and kill my performance. In 2.6.22-rc5 it will hard reset from 3.0 Gb/s to 1.5 Gb/s and operate relatively stable until heavy I/O. If anyone reading these threads (there have been quite a few in various places, see 'sata_promise error handling just a few hours ago) needs any additional information to help solve this problem, please let me know. - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
