When MA and VSA binaries are installed on AWS instance of RHEL 8.7 with Kernel version Linux 4.18.0-425.3.1.e18.x86_64, both the instances crashes with error: kernel: watchdog: BUG: soft lockup - CPU#4 stuck for 22s! [rmmod:9167].
the message from OS shows:
cvblk: loading out-of-tree module taints kernel.
cvblk: module license 'CommVault Systems' taints kernel.
Disabling lock debugging due to kernel taint
cvblk: module verification failed: signature and/or required key missing - tainting kernel
As per Commvault documentation: https://documentation.commvault.com/2022e/expert/3515_block_level_backup_for_unix_system_requirements_01.html
the supported system requirement for block-level backup is RedHat Enterprise Linux 8.6 with kernel 4.18.0-372
Similar issue was reported earlier for the above kernel version, but now it seems to be supported.
Could you please update as when it will support 4.18.0-425 kernel version.
Note: The version 4.18.0-425 works for Commserve binaries, as the instance did not crash when only server components installed.
Thanks & Regards
