So this is not the ideal fix for this problem. Anything else I can do to debug the irq lost issue? perhaps add some debug to the pcmcia code? For what its worth, I compiled a clean 2.6.22-rc5 with just the pio_polling patch added, and that allows me to mount the device without any errors in syslog. So the disable-dev_init_param-and-setxfermode-for-CFA.patch is not needed. --------------070703090404000903000409-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
