 Posted: Thu Feb 12, 2004 8:48 pm Post subject: Yenta Socket and IRQ |
 |
|
I'm running into problems with my Cardbus bridge on my Compaq Presario laptop. The only driver that works for me is the 'yenta_socket' one. When it loads I get the following from 'dmesg' | Code: | PCI: Found IRQ 9 for device 00:0a.0
Yenta IRQ list 0008, PCI irq9
Socket status: 30000010 |
When I insert my PCMCIA network card (LNT-10TN chipset) I get the two high pitched beeps, and everything seems to work (I can connect to other machines), but 'dmesg' gives me the following:- | Code: | eth0: NE2000 Compatible: io 0x300, irq 0, hw_addr 00:10:60:88:51:B3
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
NETDEV WATCHDOG: eth0: transmit timed out
eth0: Tx timed out, lost interrupt? TSR=0x43, ISR=0x3, t=97.
eth0: interrupt(s) dropped! |
When I insert my SmartMedia card reader; which 'looks' like another IDE controller to Linux (and Windows) I get the following 'dmesg', and it doesn't work :- | Code: | Hw. address read/write mismap 0
Hw. address read/write mismap 1
Hw. address read/write mismap 2
Hw. address read/write mismap 3
Hw. address read/write mismap 4
Hw. address read/write mismap 5

When I insert my 33.6K modem, I get two high beeps, and the following message from 'dmesg' :- | Code: | Hw. address read/write mismap 0
Hw. address read/write mismap 1
Hw. address read/write mismap 2
Hw. address read/write mismap 3
Hw. address read/write mismap 4
Hw. address read/write mismap 5
Trying to free free IRQ0
Serial driver version 5.05c (2001-07-08) with MANY_PORTS SHARE_IRQ SERIAL_PCI ISAPNP enabled
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS01 at port 0x02f8 (irq = 0) is a 16550A |
(ttyS00 is on the motherboard). All these cards complain about no IRQs or are given IRQ0 - whatever that is.
I've tried to look for how to set up the yenta driver but 'modinfo' gives no options for the driver :- | Code: | bash-2.05b# modinfo yenta_socket
filename: /lib/modules/2.4.20-gaming-r7/kernel/drivers/pcmcia/yenta_socket.o
description: <none>
author: <none>
license: "GPL"
bash-2.05b# modinfo -p yenta_socket
bash-2.05b# |
As you see - no options.
Does anyone have any experience of this driver or problem, and know of any way to fix it? I've had a good 'google' for this but always end up at the Linux-Kernel Archive where they speak a completely differnent language to me 
Any ideas would be most appreicated. |

I left IRQ3 available aswell, as I only have one serial port on the machine, and it now works fine - all the PCMCIA cards I have take IRQ3 everytime. Why it didn't work before I do not know! All I did was enable IRQ7 as you suggested, and IRQ3 starts to work.
Thanks very much for your help. |
