Subject: libata errors with smartctl on 2.6.24, WD3200AAKS and nVidia AHCI
Hi all,
When running smartctl to get the attributes readout libata seems to get
really confused on my system. After a timeout it recovers without apparent
ill-effect, but the reported values are complete rubbish. Unfortunately I don't
remember if this is a regression or it was always like this..
I have attached some data below, but if more is needed just shout!
Regards,
Tvrtko
