Hi,
I have got four serial ports, 16550A type, which are correctly recognized and auto-configured (even auto_irq with 2.1.124) by the kernel, but the interrupts of ttyS2 and ttyS3 don't show up in /proc/interrupts, while their ioports do. This happens with both 2.0.35 and 2.1.124. Any ideas? ttyS2 and S3 use irqs 10 and 15, respectively. 2.1.124 is compiled with serial IRQ sharing, but I use different interrupts for each because of the other OS's flaws.
emma1:/root # cat /proc/interrupts ; cat /proc/ioports | grep serial

The ports seem to work correctly, though.
