Hpsa problems

Hello,

My system worked perfectly for fews months but since 1-2 weeks I have a big issue. Sometimes, in /var/log/messages I got messages like that :

hpsa 0000:04:00.0: Abort request on C0:B0:T0:L0
hpsa 0000:04:00.0: Abort request on C0:B0:T0:L0

This cause high load average when the problem appear ( 80+ ).

I run on Debian Wheezy stable and 3.13-0.bpo.1-amd64 kernel.

Any ideas ?

Thanks
