Bug 201620

Hardware: Dell R730, with a H330 mini controller

We are using the MegaCli (from ports) tool to monitor the state of the disks. But after a reboot, it stopped working. The systems is otherwise working as expected. At the same time we see messages like these in the log:

Jul 13 01:32:51 *** kernel: mrsas0: Cannot allocate ioctl data mem
Jul 13 01:33:30 *** kernel: mrsas0: Cannot allocate ioctl data mem

Jul 13 01:34:11 *** kernel: mrsas0: Failed to get a free cmd for IOCTL

And last here are a few more details about the system:
