The last without a problem kernel was - 2.6.16 (acknowledgement to that is SLES 10 SP2 does not give high iowait on ASUS P5K). So let's look what super-mega-function has appeared in 2.6.17 and was absent in 2.6.16. This function cannot clearly belong to separately taken file system (all file systems are subject to an error). Changes in schedulers between 2.6.16-2.6.17 I has not found out. Introduction libata - a unique difference. Who gives high iowait - itself libata or the infrastructure of its embedding in a kernel practically has no value. Value has only one - the kernel is disabled. Also it is the sad fact.
