eth0 generating spurious 8259A interrupt error
Greetings.
I have searched the archives of this and other lists and looked around
with Google for this particular error.
One cause is bad hardware.
However, I think I know what is causing it on my system, I just need to
know how to work around it.
I have an old laptop. It is an IBM ThinkPad 380D with a Pentium 150 MMX
processor and 80 MB of RAM.
I had trouble even finding an old-style PC Card Ethernet adapter that
would do 10/100 instead of just 10 Mbps. The card I replaced my Xircom
PS-CE2-10 with is a Linksys EtherFast 10/100 PC Card PCMPC100.
I am wondering of the problem is caused by my laptop not being able to
handle the traffic from the Ethernet card since it is linking at 100
Mbps Full-duplex.
Here is the stuff from the end of dmesg about this card:
eth0: Asix AX88190: io 0x300, irq 3, hw_addr 00:04:5A:9D:E3:93
eth0: found link beat
eth0: autonegotiation complete: 100basetT-FD selected
spurious 8259A interrupt: IRQ7.
eth0: found link beat
eth0: autonegotiation complete: 100basetT-FD selected
eth0: too much work at interrupt, status 0x01
eth0: too much work at interrupt, status 0x01
eth0: Asix AX88190: io 0x300, irq 3, hw_addr 00:04:5A:9D:E3:93
eth0: found link beat
eth0: autonegotiation complete: 100basetT-FD selected
If it is the card causing the problems, is there some setting in the
PCMCIA subsystem I can change or something I can mofidy in an
initialization file for the Ethernet card to force it to assume
Half-duplex instead of full?
Or do you have any other advice?
Thanks!

incredibly long line of text between the "header" and "footer".
