This is a problem i solved once before, but have since converted to udev + pcmciautils from devfs + pcmcia-cs.
The problem arises from the pcmcia network card and serial mouse sharing IRQ 3:
| Code: |
# cat /proc/interrupts
CPU0
0: 1793672 XT-PIC timer
1: 1507 XT-PIC i8042
2: 0 XT-PIC cascade
3: 167 XT-PIC pcnet_cs
4: 5464 XT-PIC serial
5: 4 XT-PIC Maestro3
7: 0 XT-PIC parport0
8: 2 XT-PIC rtc
9: 0 XT-PIC acpi
11: 2 XT-PIC yenta, yenta, uhci_hcd:usb1
14: 6958 XT-PIC ide0
15: 41 XT-PIC ide1
NMI: 0
LOC: 0

As another post suggested, I added to /etc/pcmcia/config.opts. This resulted in a completely unusable irq3 (and therefore serial port):
| Code: |
# cat /proc/interrupts
CPU0
0: 1793672 XT-PIC timer
1: 1507 XT-PIC i8042
2: 0 XT-PIC cascade
4: 167 XT-PIC pcnet_cs
5: 4 XT-PIC Maestro3
7: 0 XT-PIC parport0
8: 2 XT-PIC rtc
9: 0 XT-PIC acpi
11: 2 XT-PIC yenta, yenta, uhci_hcd:usb1
14: 6958 XT-PIC ide0
15: 41 XT-PIC ide1

How do I prevent pcmciautils/udev from using IRQs 3/4 for cards? Thanks. |
