Subject: [9fans] PCMCIA Interrupt Issues
Topicbox-Message-UUID: 01675c1e-eace-11e9-9e20-41e7f4b1d025

I'm having some trouble getting networking working on a
couple of older NEC laptops.  They have the TI 1131 PCMCIA
chipsets.  The first issue that shows up (and I think this
is the root of the problem) is reported as:

#Y0: No interrupt?
i8259enable: irq 0 shared but not level
intrenable: couldn't enable irq 0, tbdf 0xC001800 for cardbus

then for the other controller:

#Y1: No interrupt?

It does find the ethernet card and it does get far enough
to send DHCP requests.  In fact I see that the DHCP server
gets the requests and sends responses, but the laptop never
seems to get them.  The card's stats do report seeing packets,
but I don't seem to ever be getting to the interrupt handler.
I'm pretty sure this isn't a driver issue since I'm seeing
it with a 3c589, a 3c575 and an EC2T.

Anybody seen anything like this?  Any suggestions on making
the PCMCIA support happy with the 1131?

Thanks in advance,
