I forgot to mention, that I have Moxa 8-port serial board (16550A). It is the only board on 10th IRQ. I use in-kernel serial driver for it. (configure with setserial).
I also use onboard /dev/ttyS0 for ppp too. > card are you using, how many serial ports, how many interrupts for > serial ports, SCSI or IDE, which network card, any special kernel 3 interrupts. irq 3,4 for ttyS{1,0}, and irq 10 for 8 posrts on Moxa. I have 3 rtl8029 based ethernet cards, and one rtl8139 based. Adaptec 2940UW-2 SCSI card. Here is my irq map: irq 0: 79541 timer irq 13: 1 fpu irq 1: 4816 keyboard irq 14: 8 ide0 irq 2: 0 cascade [4] irq 15: 56 ide1 irq 3: 1 irq 16: 20271 aic7xxx, eth0, eth3 ^^^^ That's inactive channel. eth3 - rtl8129 irq 4: 71348 serial irq 17: 2740 eth1 irq 8: 1 rtc irq 18: 821 eth2 irq 10: 1767 serial irq 19: 19307 aic7xxx irq 12: 2058 PS/2 Mouse
> drivers? No. Although papers with boardstated that there is special kernel driver, I prefer to use well tested in-kernel ones. BTW, I have Raid012345 patchset applied, I don't consider this as driver, it doesn't muck with interrupts and so on. I have 1 raid-1 mirror.
