We have a PowerEdge R510 that was solid for months, but then one morning it started to get BSODs. It was stating that there was a bad pool caller. After reviewing the mini dumps I could see that the Qlogic driver was making the requests that caused the error. The crashes would only occur when a cable was plugged into the card. The crashes will happen whenever any cable is plugged into one of the two network cards or the on-board ports. I have installed the latest firmware and drivers and it has not helped the issue.
