I'm responding to Stephan's request on 2010-09-14 for feedback on the
proposed kernel. First assumption here is that it is 2.6.35.
I have been using the stock releases of Lucid Lynx (10.0.4 and 10.04.1)
and getting the SATA errors detailed below. After installing the 2.6.35
kernel, the errors have disappeared from syslog. I can't comment on any
performance changes.
