Hi,
I've got a nasty problem with the configuration specified below.
Every couple of hours an IO errors rears its ugly head. When the error occurs
the disk powercycles, one can verify that by looking at Start_Stop_Count smart
attribute. The hardware is ok, I've got three exactly the same systems and all
show the same behaviour. I even run windows a while on one of them but never saw
an increase in the Start_Stop_Count nor any error in the event log, everything
was working ok. The error occurs on both disks, not just /dev/sdb but also
/dev/sda.
Ahci.c looks pretty up to date, it includes everything up to the "sb600 can't do
msi patch"
I'm running a minimal text only server, with CPUFREQ=no and elevator=deadline as
boot options.
If more info is needed please let me know else I hope that someone might find a
cure for this, I'm fighting this since 2.6.22!
Thank you for your interrest,
Frederik
