vmur.ff8847 Kernel function alloc_chrdev_region failed with error code <error code according to errno definitions>
Explanation
The z/VM virtual unit record device driver (vmur) needs to register a range
of character device minor numbers from 0x0000 to 0xffff.
This registration failed, probably because of memory constraints.
User response
Free some memory and reload the vmur module. If the z/VM virtual unit
record device driver has been compiled into the kernel reboot Linux.
Consider assigning more memory to your LPAR or z/VM guest virtual machine.
