Dear Gaurav..... I am not an expert on this issue, but allow me to share my idea... > 186 testl $IF_MASK,EFLAGS(%esp) # interrupts off > (exception path) ? you mean this check, right? Well IMHO, "cli" certainly masks interrupts, but line 186 above checks whether IF (Interrupt Flag) of EFLAGS saved on kernel stack is disabled. Maybe on exception path, IF flag is cleared first and the handler is called? CMIIW too regards Mulyadi -- Kernelnewbies: Help each other learn about the Linux kernel.
