It would appear so. This is inside an if line->count == 0 > #4 0xa010e458 in line_open (lines=0xa02309a0, tty=0xaf1f7000, > opts=0xa0230920) at line.c:258 and the place that decrements line->count does this: if(line->count == 0) line_disable(line, -1); which should ensure that the interrupt is disabled. Could you get stack traces from activate_fd and deactivate_fd for this irq? We need to see how the count is becoming 0 without the interrupt being turned off.
