The subject line shows the error message that I have been having. From
searching the newsgroups, archives, and the web I have discovered what
in my mind is a temporary fix, ie... sysctl -w hw.atamodes=pio,etc.....
The drive I have in my system is a Samsung SV0844D, which is an UDMA66
drive, the controller is a PIIX4 which only supports UDMA33 and
supposedly is supported properly under FBSD. I began receiving this
error after upgrading to 4-stable using cvs from the 3-stable line I was
using. Unfortunately it has caused some data corruption, but I think
I've caught most of that. My question is, is there a way to fix it
without having to use pio modes and suffer that performance hit, or need
I just wait until the driver is fixed and when will that happen?
On a seperate note, since my switch to 4-stable some of my system
monitoring tools, ie.. top, vmstat, wmmon, etc have stopped functioning
properly, the output of top and vmstat are below, wiser individuals then
me hopefully will know where I went wrong.
