Many thanks for getting back to me. I am currently using Debian Unstable (kernel 2.6.22 I think off hand), I had the same problems with Debian stable (2.6.18). At the moment I do not have remote access but I will try changing the IO scheduler and let you know.

Please cc linux-ide@xxxxxxxxxxxxxxxx I don't really keep track of libata or sata_sil versions. Which kernel version are you using? Does switching IO scheduler make any difference? -- tejun - 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
