HP P4000 SAN SANiQ 9.0 Kernel Panic Issue

At some point after 208.5 days of continuous runtime, a counter in the SAN/iQ Linux kernel may incur a divide–by–zero error that leads to a kernel panic, which causes HP P4000 storage systems running SAN/iQ software version 9.0 or 9.0.01 to go offline immediately. 

After ten minutes, the HP P4300 G2, HP P4500 G2, HP P4800 G2 and HP LeftHand DL320s storage systems will perform an Automatic Server Recovery (ASR) followed by resumed operations. Other storage systems running SAN/iQ version 9.0 or 9.0.01 will hang indefinitely until manually rebooted.

I would definitively be upgrading if it were me!
