Hey Amit,
From the log that you linked, this looks like there's corruption within
the kmalloc slab caches. Can you please try enabling slub debug? That
might give us more information about who is causing the corruption
you're seeing here.
To enable slub debug, you can add the following to your kernel config:
CONFIG_SLUB_DEBUG=y
and CONFIG_SLUB_DEBUG_ON=y or add slub_debug to the kernel command line.
