Hi, I have a PCI->PCMCIA adapter with a TI PCI1410 chip on it that I can't get to use an irq. It only boots into polling mode. Is there a way to set it? I tried setting hw.pcic.irq, but this results in "Can't route ISA CSC interrupt." I think my problem is similar to that described in 20020221.100212.55046049.imp@village.org This machine just cvsup'ed -stable, so is at 4.8-Release plus a day or two. The system is identical to one in work (anther Dell Precision 410 PII) except the work machine uses an ISA->PCMCIA adapter. This one uses a PCI->PCMCIA adapter with the TI 1410 I'm using ISA interrupt routing (hw.pcic.intr_path=1). If I don't, the system hangs at boot after printing "pci_cftintr_virgin: using routable interrupt 3" I tried one kernel configured like the man page device card device pcic and another configured like LINT/GENERIC device card device pcic0 at isa? irq 10 port 0x3e0 iomem 0xd8000 Memory addresses of 0xd0000 and 0xd4000 result in PIOCRWMEM invalid argument errors. Using 0xd8000 the Orinoco Gold card is seen and will associate. I just can't use it and see constant wi timeout messages. >From what I read in the archives, my problem relates to being in polling mode. So I'm currently looking to set an IRQ for this pci->pcmcia bridge to see if this fixes anything. Any ideas? If it helps, the "AP" is another FreeBSD system (using a PLM based adapter, not cardbus) so if there are things I can look at on the "other end" let me know. One other item. The machine in question dual boots Win2K (quicken/turbotax) and talks to the FreeBSD AP just fine. All the HW works. I've also set wireless up on FreeBSD using ISA->PCMCIA, PCI->PCMCIA w/PLM (e.g. no pcic) and on Soekris (e.g. no (bus)->PCMCIA adapter. I just can't get this current configuration to behave. Any help appriciated. Thanks, MikeC
