In disabling interrupt synchronization method, a process must disable interrupt just after entering a critical section and re-enable it just before leaving it. In a multiprocessor system, a particular process P1 disables interrupt after entering a critical section by using one CPU and meanwhile another CPU has interrupt enable flag set to 0. Another process P2 wants to enter the critical section by using any of the two CPUs. Suggest what could occur in this scenario.

Question
In disabling interrupt synchronization method, a process must disable interrupt just after
entering a critical section and re-enable it just before leaving it. In a multiprocessor
system, a particular process P1 disables interrupt after entering a critical section by
using one CPU and meanwhile another CPU has interrupt enable flag set to 0. Another
process P2 wants to enter the critical section by using any of the two CPUs. Suggest
what could occur in this scenario.
