Hi What may happen on a SMP machine if a serial port has been closed and the closing stage is at shutdown() in serial.c in the call to free_IRQ and BEFORE the IRQ is really shutdown, a new character arrives which causes an IRQ? Is it possible that the OTHER cpu takes this interrupt and causes a

Re: Q serial.c

From: Jonathan Lundell [EMAIL PROTECTED] The other CPU servicing the interrupt, was the question. cli() doesn't affect that. This could presumably happen if shutdown() gets run on a non-interrupt-servicing CPU, or if interrupts are dynamically routed (eg round-robin). Ah. Missed that. Hm.
