Hi Chandrakanth,
There seems to be an issue from a call within the megaraid_sas driver
[ 1.004130] megaraid_sas 0000:07:00.0: requested/available msix 16/16
poll_queue 0
[ 1.004154] ------------[ cut here ]------------

[ 268.058027] index -1 is out of range for type 'cpumask *[1024]'
This is the offending line of code located at
plucky/arch/x86/include/asm/topology.h:72:28
69 /* Returns a pointer to the cpumask of CPUs on Node 'node'. */
70 static inline const struct cpumask *cpumask_of_node(int node)
71 {
72 return node_to_cpumask_map[node];
73 }
Are there any additional patches within megaraid_sas that addresses this issue
"UBSAN: array-index-out-of-bounds"?

[Impact]
We can see that the megaraid_sas driver inbox version in the 24.04.02 point
kernel is 07.727.03.00-rc1 which is old. We would request to include the
following megaraid_sas driver patch set in the upcoming 24.04.03 point release
(tentative release is on June-July).

[Test Plan]
- Driver load/unlaod
- virtual drive creation (R0, R1) and deletion
- JBOD creation and deletion
- IO run with different profiles (4k...1M) on VDs and JBODs,
- Controller reset while running IOs
- Event handling
