------- Comment From [email protected] 2018-05-04 11:10 EDT------- We could not able to install 'sar' package due to 166588 prior patch. And also 'xfs' was being used on the system from the prior run. To overcome both, we planned fresh installation . Installed latest ubutnu1804 kernel(4.15.0-20) on LSI disk and booted up with disk. Login prompt appears & gave credentials. Immediately in less than a minute, system dump messages and started rebooting. Its not allowing time to run anything on the console prompt.
Tried multiple attempts to boot with the latest kernel & once logged in system is rebooting with call traces as below.
