Subject: Re: SATA Cold Boot problems on >2.6.25 with NV

Hello!

The patch before, I told it always boots but the last two days I had
much difficulties to boot. It was hard resetting and waiting a couple of
times before bailing out with no mountable root FS. 

One time it was switched off three hours and the next time overnight, I
powercyced a couple of times. If I am the only one experiencing this
difficulties (am I the only one with this chipset/revision reporting?),
shouldn't we consider this machine... broken? I change SATA cables from
time to time, but these seem all to be okay. I mean, if it is really
_that_ strange...
