I am trying out out a PCI-PCMCIA adapter which uses a TI chip (Elan P111). Using RedHat 6.1 + PCMCIA 3.1.8
My problem is the response time is poor - the cards install ok but ethernet ping is 20ms (ne) and Wireless Lan (Breezecom) can be anything from 120 ms to 1000 ms. The same cards in an old 486 laptop Win95) give respectively normal ping times.
I suspect the problem is associated with the adapter PCI interrupt, /proc/interrupts shows the PCMCIA card, but nothing for the adapter (is this normal?). lspci shows the following for the adapter:
00:12.0 CardBus bridge: Texas Instruments: unknown device ac50 (rev 01)
I have tried PCIC_OPTS="pci_int=1 irq_mode=3" and a number of other combinations - nothing seems to make any difference.
Can anyone suggest where I am going wrong?
