Re: [sata] libata update

[Henrik Gustafsson <lkml@fnord.se>]

(sorry for screwing with the thread, I was not subscribed when I read the 
original post)

The patch seems to work just fine. It's been running for six hours now 
with varying amounts of load and no catastrophes has occurred so far.

Only things are these lines saying 'abnormal status' (which has been there 
all along). I assume the codes mean 'device not present' (which would be 
correct, at least in my case) or something similar, but I don't know for 
sure so I leave it to someone better informed to patch :)

(also, there is the 'Unknown device'-thing in my lspci, but that's neither 
related to libata nor is it a 'real' problem)

Using a Promise FastTrack S150 SX4
Relevant piece of my dmesg, lspci follows (just let me know if you need 
the rest)
