At random times while using a Dell T5810 Precision Workstation (Windows 10 Pro 64-bit) I get  a System Stop blue screen. The code is
DRIVER_IRQL_NOT_LESS_OR_EQUAL and the failed device is iastorb.sys.

A minidump file is attached.

The system reboots on its own. I've seen it maybe three times over the past couple weeks. There are no hardware or software changes I know of that were done just before this problem started occurring. (I just removed an internal SATA data drive and added a new external hard drive but this crash problem started before then.)

The hard drive configuration has two sk Hynix 1TB SSDs on a PCIe 3.0 x16 expansion card. Drives are NOT in any RAID configuration. There are no drives connected to the SATA ports on the motherboard. Intel Rapid Storage Technology Enterprise is installed on the computer.

The external drive (Western Digital Gold 4TB WD4002FYYZ) connects through a StarTech docking station to a rear USB3 port.

I ran the Intel Driver & Support Assistant and the Dell update checker. They say all drivers are current.

Device Manager shows no devices with problems. In System Information no problem devices are listed.

Do I need iaStorB and iaStorA?

Assuming I do need them, any suggestions how to troubleshoot this problem?

Thanks, Pete
