PCMCIA=yes
PCIC=i82365 ( found via probe -m )
PCIC_OPTS="cs_irq=11 pci_irq_list=11,11 do_scan=0" ( you see i want to force irq 11 )
CORE_OPTS=

What ever i try, irq 13 is always taken. And why is there also a relation with irq 14?
I get a lot of error on the HDA. Eventualy the systems become horrible slow and locks up.
Windows 98 on this system works perfectly. But i want 100% linux on this machine with network support.
any help is welcome.

axnet_cs
AXNET_CS(4) Kernel Interfaces Manual AXNET_CS(4)
NAME
axnet_cs - Asix AX88190 chipset PCMCIA Ethernet Driver
SYNOPSIS
insmod axnet_cs.o [pc_debug=n] [irq_list=i,j,...]
DESCRIPTION
Axnet_cs is a driver for PCMCIA ethernet cards based on the Asix AX88190 chipset. These cards are mostly NE2000 compatible but have sev-
eral bugs that are sufficiently tricky to work around that a separate driver was deemed necessary. When this driver is bound to a card, it
allocates the next available ethernet device (eth0..eth#). This device name will be reported in the kernel log file, and passed on to
cardmgr(8).
PARAMETERS
pc_debug=n
Selects the PCMCIA debugging level. This parameter is only available if the module is compiled with debugging enabled. A non-zero
value enables debugging.
irq_list=i,j,...
Specifies the set of interrupts that may be allocated by this driver.
DIAGNOSTICS
axnet_cs: this is not an AX88190 card!
Indicates that this card is probably a normal NE2000 compatible card, which requires the pcnet_cs driver.
eth#: interrupt(s) dropped!
Indicates that the driver did not receive an interrupt notification for some reason. The driver will poll the card (with a signifi-
cant performance penalty) if the problem persists. The most likely cause is an interrupt conflict and/or host bridge configuration
problem.
