Yes, I did, and it has since been documented in the PCMCIA HOWTO, section 2.3, subsection "Card readers for desktop systems": For Chase CardPORT and Altec ISA card readers using the Cirrus PD6722 ISA-to-PCMCIA bridge, the i82365 driver should be loaded with a ``has_ring=0'' parameter to prevent irq 15 conflicts. I had been trying the option "has_ring=1", which I didn't know was the default. [ CC'ed linux-kernel so that this gets into its archives.

I had no problem with one and the same pcmcia_cs package with a 2.2.9 kernel which locked up ALL of the 2.4 kernels I tried meanwile (I am on 2.4.18 now using the kernel-owned pcmcia modules, yenta_socket, which does not seem to know any parameters at all). Today I found a hint on giving the kernel an irqmask on bootup in the lilo.conf file: append="pci=irqmask=0xafff" This prevents the vital IRQs of ide or mouse from being taken by the PCI bridge when the yenta_socket or i82365 module is loaded. (Unloading the module again would not give back interrupt control - so a reboot was the final step) Charles Briscoe-Smith wrote: > > Personal question: did you find a solution? > > Yes, I did, and it has since been documented in the PCMCIA HOWTO, > section 2.3, subsection "Card readers for desktop systems": > > For Chase CardPORT and Altec ISA card readers using the Cirrus PD6722 > ISA-to-PCMCIA bridge, the i82365 driver should be loaded with a > ``has_ring=0'' parameter to prevent irq 15 conflicts. > > I had been trying the option "has_ring=1", which I didn't know was > the default. > > [ CC'ed linux-kernel so that this gets into its archives.
