Question ToPIC100 + 3c589 RequestIRQ Failure (2.4.0-test7,3.1.19) 

Forum: 3Com PCMCIA Ethernet Adapter Issues
Date: 2000, Aug 27
From: Andreas F. Bobak bobak

On my Toshiba 3480CT, using kernel 2.4.0-test7 and pcmcia-cs 3.1.19, my 3com 589D card fails to load with "3c589_cs: RequestIRQ: Resource in use". When I boot into kernel 2.2.16 (RedHat 6.2) the ethernet card works without any flaws.

The Portege 3480CT uses a ToPIC100 PCI->CardBus bridge, the assigned IRQ is 11.

I played around with irq_list settings in /etc/sysconfig/pcmcia (PCIC_OPTS) and as opts for the modules, with no effect. I just don't get it...

Any idea how I can make it work?

These are the logfile excerpts:
