[AYAN KUMAR HALDER]

> Could you post the full backtrace (straight from the kernel log)?
The backtrace has been obtained from a debugger, not from the kernel
log (as the kernel has been deadlocked). The backtrace is as follows:-

arch_spin_lock
_raw_spin_lock
vprintk_emit
vprintk_default
printk
smp_init
do_initcall_level
do_initcalls
do_basic_setup
kernel_init_freeable
kernel_init
ret_from_fork
