Re: [leaf-wisp] Using Senao card (former using several...)

You have also to set "PCIC" if you want to set your own PCIC_OPTS.

Try using the following PCIC_OPTS:
irq_mode=0 pci_csc=0 poll_interval=100

where no interrupt is catched by hostap_cs which suggests an interrupt problem with the PCI-PCMCIA bridge.
I tried at /etc/default/pcmcia the following entries:

PCIC_OPTS='irq_mode=0'

PCIC_OPTS='irq_mode=1'

PCIC_OPTS='irq_mode=1 irq_list=0'

PCIC_OPTS='irq_mode=1 irq_list=0 extra_sockets=1'

but I get the same output from iwconfig after restarting pcmcia subsystem.
So it seems the problem is interurpt related but I don't know how to isolate the problem and solve it.
What do you suggest I can do?
Thanks a lot.

Looks like an IRQ problem. Check /proc/interrupts

The card is Senao NL-2511CD+EX2 w/PCI-PCMCIA adapter.

Any idea to diagnose this appreciated.
