i'm not sure if i understand the terminology here so please correct me if i am wrong: the KernelMainlineBuilds page pointed me to http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/
so i downloaded the following version: 2.6.34-999.201005041005
both test runs resulted in ata6 errors similar to 2.6.32

however, now i'm not so sure the 2.6.33 is any better. previously i only looked at the logs and they seemed okay because there were no errors - but now i see that all my 2.6.33 boots produced in kern.log was:

May 4 14:42:14 ubuntu kernel: Kernel logging (proc) stopped.
May 4 14:43:31 ubuntu kernel: imklog: Cannot read proc file system, 1.

and there ARE ata-related errors in 2.6.33 dmesg (interestingly, they now refer to ata4 instead of ata6 and i only have one hard drive)

so the only thing i know for sure is:
- there were no such errors before upgrading to lucid (kernels before 2.6.31)
- the only crash + I/O error, dev sda, happened in 2.6.32

do these errors messages mean the sata driver is doing something to prevent something bad happening? or do they indicate that something bad has happened already? no idea... i'm just reporting what i see.
