Rogue Wave Software Centos 7.3 image kernel breaking LIS integration

[johanburati]

I tried to install LIS 4.1.3-2 on a VM build from the Centos 7.3 from Rogue Wave Software,
using kernel 3.10.0-514.16.1.el7.x86_64, and after reboot the VM hangs and fails to boot.

All LIS modules report unknown symbols at boot time, including storvsc, which fails to load. This leads to dracut-initqueue timeout messages.

A few sample boot messages for reference:

[ 3.294211] hv_storvsc: disagrees about version of symbol vmbus_driver_unregister
[ 3.294212] hv_storvsc: Unknown symbol vmbus_driver_unregister (err -22)
[ 3.294250] hv_storvsc: disagrees about version of symbol vmbus_sendpacket
[ 3.294251] hv_storvsc: Unknown symbol vmbus_sendpacket (err -22)
[ 3.294259] hv_storvsc: disagrees about version of symbol vmbus_close
[ 3.294260] hv_storvsc: Unknown symbol vmbus_close (err -22)
[ 3.294263] hv_storvsc: disagrees about version of symbol vmbus_recvpacket
[ 3.294263] hv_storvsc: Unknown symbol vmbus_recvpacket (err -22)
[ 3.294276] hv_storvsc: disagrees about version of symbol vmbus_open
[ 3.294277] hv_storvsc: Unknown symbol vmbus_open (err -22)

LIS 4.2.0 fixes this issue. The kABI change came in at the end of the 4.2.0 development cycle.

The next release, 4.2.3, adds compatibility for the 7.4 kernels.
