next in thread | raw e-mail | index | archive | help
I'm having these kind of errors on a IBM x220 series server specially when i've
a lot of disk accesses in a short time. The error are not 'fatal' cause the
system don't crash nor the application, so i'm quite fine but i cannot
understand what these messages are. I've tried to change the cable and
termination but the messages still here.
Any hint is appreciated.
